자주 묻는 질문
Quick answers.
›Are these passwords truly random?
Yes. We use the same secure random source your browser already uses for encryption — there's no pattern an attacker could guess.
›Are the passwords saved anywhere?
No. Generation happens entirely on your device. We never see the passwords, never log them, and never send them over the network.
›How long should a password be?
12 characters is the bare minimum. 16 or more is what we'd recommend for anything sensitive (email, banking, password manager). Longer is always stronger.
›What does the 'Include a word' option do?
If you turn it on, we hide a word you choose somewhere inside the otherwise-random password — so you have something familiar to remember. The rest of the characters stay random, which keeps the password strong. Pick a word that's meaningless to anyone but you.
›Doesn't including a word make the password weaker?
Slightly, but not by much when the password is long enough. A 20-character password with a 6-letter word still has 14 random characters around it — far stronger than a typical password. Don't use a guessable word like your name or 'password'.
›Should I use a password manager instead?
Yes — for the long term, a password manager like 1Password or Bitwarden is the right answer. Use this generator to create the passwords your manager stores, and to make a strong master password you'll actually remember.
›Why skip 'confusing characters' like l, I, 1, O, 0?
Because they're easy to mistype when you have to read a password off a screen and type it on a phone or another device. Turn this on if you'll ever need to type the password by hand.
›What's the difference between a password and a passphrase?
A passphrase is several real words strung together, like 'correct-horse-battery-staple'. It's easier to remember but needs to be longer to be equally strong. Both can be secure when used correctly.
›Can I use these for Wi-Fi passwords?
Yes — but turn off 'symbols' if your router rejects them, and aim for 16+ characters. Wi-Fi passwords are usually typed once per device, so memorability matters less.
›Is the generator free?
Yes — fully free, no signup, no ads, no upsells.
