Nowadays, most people use password managers (hopefully). However, there are still some passwords that you need to memorize, like master password (for a password manager), phone lock, wifi password, etc.
Security wise, can passphrase reach the strength of a good password without getting so long that it defeats the purpose of even using it?
Sure. You can either increase the dictionary of possible words, or increase the number of words or both. Eventually it will become unwieldy. I don’t bother with passphrases though.
I generate passwords of sufficient entropy (random ASCII), store them securely (encrypted, key memorized, on dedicated hardware), and never re-use them. I don’t trust password managers unless open-source. I don’t need convenience – to some extent, it’s my job to manage other people’s secrets. Since I’m being paid, no need for shortcuts.
Same. Pass phrases seem like a solution to a problem that doesn’t exist anymore. We don’t live in a world where people should be reusing and memorizing strong passwords. We live in a world with frequent user data theft and scams to glean your login info. Just last week, I started getting random login attempts from around the world for a Microsoft account I haven’t used in over a decade. No idea when or how that info got leaked.
And people aren’t equipped to memorize a different passphrase for all 30 of their accounts.
So, we should do what we always do: Get machines to make the issue easier for us to manage. Right now, that means password managers with a strong master password and secure storage.
In the future, maybe we’ll have some kind of creepy central government ID based password-less login method. Who knows?
Edit: Besides, most services require ThIrTeEn dIgIt lOnG PaSsWoRdS WiTh fIvE SpEcIaL ChArAcTeRs aNd sIx nOn-cOnSeCuTiVe dIgItS Of pI ThAt dOeSn’t mAtCh aNy kNoWn dAtE Or eVeNt oR SpEcIaL StRiNg oF NuMbErS. It’s just too annoying, and I’d have to memorize all the special characters in addition to the phrase.
OP kinda already addressed that. A password manager is great, but you still need a master password, so do you use a passphrase for that?
Yeah, I hate that. Forcing me to input special characters makes my password slightly less secure. Of course I’ll include them by default, but now an attacker can eliminate all passwords without special characters. Most people just put the number 1 or a period at the end of their existing, frequently re-used password anyway. Or capitalize the first or last letter. So it doesn’t make it really harder to crack dumb passwords.
It’s like we’ve optimized passwords to be hard for humans to remember, but easy for humans to guess!
Those government id based login methods are quite common and very secure. Belgium has a system that used your ID, your phone number and your phone to verify your login. A lot of EU banks have been using a OTP generated by a dedicated hardware that looks like a tiny calculator. The Netherlands has a dedicated app that is verified by your government id and that uses a qr to verify your identity.
They can be good quality, yeah. But I’m more worried about having to basically present a digital-equivalent of a driver’s license if I want to sign up for Netflix, or watch porn, or order food. And if ID system routes every request to a central location first, then you get stuck with de-facto tracking on everything you ever do, no matter how good the company’s privacy record is. That’s what I meant by creepy.
Thank God for GDPR. That would be impossible in the EU. ID’s can only used in very specific cases that are detailed in the law.
No, I just memorize the proper password.
All my manual passwords are passphrases.
This is basically based on the idea that if the password is so strong I can no longer input it, it has no inherent value anyways. A phrase makes it easier to use entire sentences as a password and readily recall them.
Of course, these are but a minority, the rest are passkeys or passwords a manager will fill in.
I do use a password manager, and a lot of my passwords are automatically generated piles of random ASCII.
There are of course passwords I have to key manually a lot; especially the master key of my password database. I often use pass phrases for these. The ones I have to commit to memory, or even need to key manually reading with my eyes from my database, or in the case of my Wi-Fi passwords tell to other people, I make these fairly human readable/typeable. Trying to key lFqvC3]gI~l8p2V6TvTY&p in is a pain in the ass even in a font that renders that uppercase I and lowercase L as different glyphs. Something like corrEct_horse battery staPle, well I worked in an underscore and two capitals in something I can still touch type pretty effectively. Don’t use correct horse battery staple as a password; it’s burned.
I do use passphrases, but I combine with randomness.
I memorize one random 8 character string to use with something more memorable.
Then when I need more security, or I feel that random 8 character string is no longer safe (password leak/hacked), I memorize a new 8 character string.
Then I combine them.
Then I memorize a new 8 character string and mix it in.
It’s a process built up over years that ingrains into memory. Sometimes I forget the order, or if i added spaces, or did no spaces. Luckily, as long as I am sure of the discrete segments, I can remix them to recreate until it works (in a reasonable time).
My last addition was when I made the move from Lastpass to another password manager, after their endless bad news.
I use a short passphrase that I made up that only I and my husband know. It consists of numbers, a special character, a word, and more numbers.
Then whatever I’m logging in to, my password consists of something relevant to the thing, with my passphrase appended to it.
I found it amusing when the security team in my company sent me parts of my password in plaintext saying it was insecure (because it didn’t have special characters in it) and recommended I use a password manager
The account is used for the ancient VPN software and all of our ssh management tools
And windows login if you’re using windows.
Yeah good luck using a randomly generated password that you have to type in multiple times everyday
The account is used for the ancient VPN software and all of our ssh management tools
And windows login if you’re using windows.
If you’re using one password for all those things, you’re doing it wrong. Even if the passphrases you pick are easy to remember and type, they should be distinct.
If it’s one “account” then it likely has only one password.
That’s SSO for you
Isn’t the bigger issue here that they can see the plaintext password?
Yeah I actually gave them shit about it and they just handwaved it away
Ok, this is a reasonable community to ask. What’s a FOSS pword manager that is easy to use, reliable, likely to be around and working in 5 years, and won’t leave me feeling shit up a creek if my phone dies or I’m using a public terminal with software installation restrictions? Been a few years, but I had not found something that worked well for me.
What’s a FOSS pword manager
There are probably more that these two out there but the two I know of that fit this bill are Bitwarden and KeePass. The latter comes in two flavors, the original KeePass that kinda looks like shit and tries to stay lean and defer niche features to plugins, and the fork KeePassXC that tries to give it a sleeker UX with more features natively baked-in. I will refer to both simply as “KeePass” for the rest of this comment.
that is easy to use
“Easy to use” is relative. If you’re savvy enough to know what FOSS software even is, to care about using it, and to find your way onto an experimental platform like Lemmy to ask about it, I’d say youre more than capable of handling either of the above choices with ease.
reliable, likely to be around and working in 5 years
I’d wager that on both Bitwarden and KeePass.
and won’t leave me feeling shit up a creek if my phone dies or I’m using a public terminal with software installation restrictions
Bitwarden offers free cloud hosting and a web interface. As long as you have access to a browser and an Internet connection, you have access to your Bitwarden key store.
KeePass is offline-only and requires specialized client software to read its key store file format. Though, since all it is is a file, you can use simple and straightforward methods to make it accessible wherever you need it. Copy it to a flash drive. SCP it between devices. Put it on a cloud service like Dropbox. You have options. It’s just up to you to use them.
Bitwarden also lets you save locally stored files and manage them like KeePass, if you’re into that.
Honestly, since each can be made to more or less behave like the other, which one you pick largely comes down to taste. Bitwarden is more turn-key if you want cloud hosting, KeePass makes you work for it. Bitwarden is a company providing a premium service you can buy, while KeePass is a completely free project funded only by good will donations.
I prefer KeePassXC, personally.
Or if you want to selfhost, use Vaultwarden (compatible with Bitwarden official clients)
this, just works and very easy to use and backup if using docker.
I have one that I like to imagine as secure as fully randomised passwords. It’s four words but, because I’m a cool pwnz0r, the second and last word are written in leetspeak. The phrase is super easy for me to remember and the leetspeak portion has become muscle memory by now. But I only use it for my password manager. For everything else it depends if there’s a good chance I’ll need to login via my phone (no pw manager there). If yes, I use one of my couple rather-safe passwords. If no, I’ll let KeePass2 go to town with a random one.
Oh and I’m subscribed to the haveibeenpwned leakletter, so i know as soon as possible when definitely to change my password.

can passphrase reach the strength of a good password
Relevant xkcd: https://xkcd.com/936/
I’d love to hear from someone well versed in security if this is legit or significant weaknesses exist, but the math seems to check out as far as I can tell.
Dictionary attacks have been around for a long time, but It’s still quite strong especially if you throw in a number.
A fully random 8 character password has about 10^14 brute force combinations (assuming upper and lower case + the normal special characters). 4 words choosen at random from the top 3000 words (which is a very small vocabulary really) is 10^13 dictionary attack combinations, add a single number or account for variations in word style (I.e maybe don’t always use camel case) and you’ve matched the difficulty. If you use 5 words it’s 10^17 combinations.
(This is basicly copy pasted from a comment I made earlier)

If your services are storing passwords properly with a salt, dictionary attacks (including rainbow tables) are just as time-consuming to perform, since the salt renders each password hash unique; even for the same passwords.
So the same principle still stands; the longer your password, the longer to guess - as long as the encryption-at-rest is done correctly.
i also dont really get it. the bitwarden pw tester says it will take 14 years to crack “its.a.beautiful.day”, write beautiful with 2 t`s and it will take “centuries”? 🧐
but yes i still use them. but always with numbers and random characters in between and words from multiple languages or fantasy words.
That would be because the pattern on the first password are correctly spelled words and the way passwords are cracked offline (when there’s a leak of data being sold somewhere) is that they use dictionary attacks.
This means that a big file containing all known words, and can also include known used passwords from past leaks, is used to try a lot of combinations. A combination of good words that appear 1:1 in these word lists will score way lower in terms of difficulty for a computer to crack. A simple script can add spaces and periods (like your example) between words and they WOULD get your password. By adding only one random character that doesn’t fit a pattern (just like your second ‘t’), you basically force the cracker to try all possible combinations of all characters for the length of your password, which is WAY more difficult.
TLDR: There are more combinations of aaaaaaa, aaaaaab, aaaaaac then there are of matching words together for the same length of password (one.one, one.two, one.three)
In other words, don’t use “correct horse battery staple” because that’s probably in every word list by now
but even 14 years seems long for a pharase that is said and written millions of times per day. and if those crackers can make billions of guesses per second how can they not guess both variants within minutes?
related question. how to make a good password bettter? adding a few extra special symbols like “µ£₹” or one long word like “freshwatercrocodiletesticles”?
For what a civilian target would worry about, using sufficiently long passwords is your best defense. Complexity is barely important.
111111111111111111111111111.1111 is an excellent password.
Everyone should Ctrl+f their password here. But also wait the 10 minutes it’ll take to load the whole thing.
If your pw is on this list, change it immediately.
If it’s less than 8 chars? Change immediately. If it’s less than 10 chars? Change… Now.
If it’s less than 14 chars, consider just making your password longer.
This advice will save more people in its simplicity than saying more.
Want a smidge more?
If you’re paranoid, take a password that you think is decent, then insert it here, then use the output as your password.
Most times, pws aren’t stored in plain text, they’re stored using that algorithm. So, if your password is ‘password’, hackers night easily be able to see that your passwords encrypted value is exactly what that link will output if you put in ‘password’. If your password is on that huge list from the beginning of the post, they can easily decrypt the encrypted password, because these passwords’s hashes are known.
So, use the hash itself as a password.
Hell, throw a comma at the beginning to throw it off.
In terms of security? Sure. We’re talking about password entropy here.
My cybersecurity prof at uni showed us this xkcd during class lol
That’s basically a Diceware passphrase. And, it’s kinda ok. The amount of entropy is pretty significant (close to what the comic lists, if the Wikipedia article has it right). And it’s really easy to add more entropy. I often recommend passphrases to my users (I work in Cybersecurity) and use them myself. Take a sentence, with spaces, capitals and punctuation. Now throw in a few numbers for fun and stop worrying about brute force attacks, until some idiot decides unsalted MD5 is perfectly fine for storing passwords. Most such passphrases will blow right past the 4 words in that comic and are very easy to remember. Even better, make that the passphrase for your password vault (oh look a plug for KeePass). Then have the rest of your passwords all be unique, 20 character jumbles of letters, numbers, and special characters.
Also, enable Two-Factor Authentication (2FA) wherever possible. Even if it’s just a One Time Password (OTP) sent via SMS (which is a shit way to do 2FA), that’s better than no 2FA.
Yes, I use passphrases for stuff like my password manager, my computer login, and my disk encryption. For my login (which I type a lot) it’s four words; for occasional stuff like disk encryption it’s six. I’m sold on the argument that a passphrase is way easier to memorize compared to a comparably-secure random password.
The number of possible passphrases is the number of words in the dictionary you use to generate passphrases raised to the power of the number of words in your passphrase (assuming a small chance of reusing the same word in a passphrase). I use this command to generate a random phrase using my stock OS word list:
grep -v '[^a-z]' $WORDLIST | shuf --random-source=/dev/urandom | head -n5 | paste -sd ' 'grep -v '[^a-z]' $WORDLISTfilters out words with apostrophes or other weirdness. On my system the filtered list is 77,866 words.For four words, 77,866 ^ 4 ≈ 3.7 × 10^19 possible passphrases.
Compare that to randomly-generated passwords. I’ll assume that random lowercase & uppercase letters, numbers, and symbols add up to 46 characters. The number of combinations is 46^n where n is the length of the password. A four-word passphrase is the same order of magnitude as secure as a 12-character password, which has about 9 × 10^19 possible combinations.
I’m sure that if you make up your own passphrases instead of randomly generating them then the security is much lower.
Very similar heuristic here, insofar as when to use passphrases and how long.
LUKS and Bitlocker volumes get 8 words, computer logins usually get 4 words (potentially more depending on frequency/criticality of system).
Smartcards and mobile devices do have numeric pins due to frequency of use and relative difficulty in copying those for offline attacks.
Websites that are filled in w/ password manager get passwords get the random symbol-laden strings that ‘meet requirements’
I use a leetified (using my own custom flavor) passphrase as my master password - I can type it really quickly and it’s obscure as hell so I’m happy with it.
most people use password managers
You don’t know many boomers, do you?
According to security.org survey data, in 2021, 22% of Americans said they used a password manager, but in 2023, the percentage increased to 34% with a further 10% of users saying they use a security passkey or other physical password device.
So in the most generous interpretation of that, just over half of people are not doing anything secure.
I’m a big car guy so I typically use car makes and models but never ones I actually own, usually I’ll go with some like SubaruImprezaWrxSti2012 except I scramble the order of the words and throw the year in a random position. This is really easy to remember while also being long and insane enough to be difficult to guess.
Define ‘strength’… against a dictionary attack? Brute force? Social engineering? ‘forgotten password/recovery questions’ hack? Stolen session cookie? Keyloggers?
If you’re not aware of the above, take some time to learn about each of those things and how good security practices counter each one.
The question is kind of like, ‘can you bake a cake?’ … probably yes, but it’s really missing a lot of essential information, like what kind of oven, what ingredients do you have, what’s your skill level, do you have arms, etc.
Any ‘passphrase’ can be secure or insecure, depending on the other surrounding factors. 2FA solves many security weaknesses.
forgotten password/recovery questions
This is the security industry’s dirty little secret that doesn’t get talked about in public enough.
All the excellent security on a site, including complex passwords, perfectly secure storage of a salted hash of that password, multifactor authentication using TOTP, etc., is completely moot if someone can just hit “I forgot my password” (or “I don’t have my second factor”) and bypass it by doing an email loop. You instead rely on the security of the user’s email account.
for email there is an easy solution. create a shared alias on addy, confirm it as your recovery email, forget the alias 👌
