Are you using passphrases? Is it worth it? (discuss.tchncs.de)

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?

I use passphrases for frequently used logins and randomly-generated passwords of varying lengths for everything else. I also use a hardware key and/or 2FA for everything that allows it.

I'm conversationally fluent in a few different languages (enough to order food, greet people and ask directions to the shitter, anyway) and I can swear in another half-dozen languages so I tend to mix'n'match my passphrases with different foreign words. Bonus points for accented characters. That's probably not gonna fool a dictionary-based attack but since I live in a (mostly) English-speaking country, it might make it interesting for the English-only speakers to try guessing.

At work, we're held to the outdated policy set by the IT department so it can be difficult to be creative. On top of that, they force a password change whenever someone sneezes so I see a lot of sticky notes on monitors and under keyboards.

Edit: spelling and grammar.

I once had to change a password every 30 days.

And it couldn't be a password I'd used before. Along with ridiculous requirements (but not as ridiculous as the 30 day thing).

You'd think it was a password to get into the NSA's database or something.

Nope, just a (not very) random website.
