MODERATORS
Several points
They generate strong passwords - completely random with no scheme or method to guess. They are long and use many different characters. These won't be easy to memorize, but that's the point of a password manager, isn't it? Much stronger than "google-monkey123", "lemmy-monkey123" etc.
They generate unique passwords - different passwords for every login. When, inevitably, one website had their database breached and it turns out that they stored the passwords too (you never store the passwords, only a "hash", a scrambled version of it), that password of yours can't be used on other websites. Or any scheme be detected "hey that guy just appends 'monkey123' to the name of the site!" That password was truly unique and is not a danger to your other online accounts.
They protect you from phishing - consider this scenario: you get a message with a link, you click on it and the site asks you to log in, so you type in your login and password, but that was a phishing site, it looked like the real website, but really it wasn't. And now the attacker knows your username and password. A password manager that automatically fills your login details will only do so if the domain name is exactly correct, on a phishing site it will not auto-fill, giving you a moment to stop and think.
Thank you! Is it possible for a password manager to be breached?
That depends on the password manager.
There are password managers that work on your computer and the data never leaves your hardware. KeepassXC for example. The database is just a file on your computer - you are in charge of backing it up, synchronizing it to your other devices (i.e. phone) etc. The database file is fully encrypted so you could share it with a cloud provider like google drive or dropbox, or you could use syncthing which synchronizes files between your devices without cloud storage. If you use cloud storage there's a small risk that the encrypted file gets into the wrong hands (but it is encrypted so it's most likely worthless to any would be hacker).
Some other password managers offer a web service where you can log into a website to see your passwords, and they have mobile apps and browser extensions. These do store your passwords in their cloud - the risk that those get breached is considerably higher. But even there it depends on the implementation details. Bitwarden for example kind of does something similar to keepass, where your "vault" is encrypted locally and then stored on their servers. Even if they get breached, the data would be useless. Lastpass had a breach recently and it turned out that they didn't encrypt everything - so someone with access to the data could determine some details such as which sites a user had accounts on. And apparently some vaults used a weaker encryption so those might be decrypted eventually.
And a lot of password managers are closed source so there's no telling what they may do, just "trust me bro".
If I had to give a recommendation it would be bitwarden - it's open source, it's free although there is a paid plan if you need it and want to support them. It's really easy to use. If you have extreme paranoia (no judgement) then keepassxc - it's also open source and free, it's just a little more effort to set it all up so it doesn't get my first choice.
Wow—thank you for such a detailed response! This definitely gives me a better idea of the differences and how they work. I’ll give Bitwarden a try. I see it recommended several times in other responses and your detailed description gives me confidence you know what you’re talking about. Thank you again!
No, or, it shouldn't be if you're using a good one. The only way to decrypt your passwords is with your master key. If your master key is safe, then your passwords are too.
