Password tips that actually matter

Password generator FAQ

Is it safe to generate passwords on a website?

Yes — with this one, because everything happens locally in your browser. The password is generated with your device's cryptographic random number generator and is never sent over the network, logged, or stored. You can verify this by disconnecting from the internet: the generator keeps working.

How long should my password be?

At least 12 characters for everyday accounts, 16+ for important ones like email and banking. The strength meter above shows the entropy in bits — aim for 80+ bits for anything that matters.

Are word-based passwords really secure?

Yes, if the words are random. Four random words from a 7,776-word list gives about 51 bits of entropy — comparable to a 9-character random password — while being far easier to remember and type. Don't use song lyrics or quotes; the randomness is what makes it strong.

Should I change my passwords regularly?

Not anymore — current guidance (including NIST) says forced rotation leads to weaker passwords. Change a password when there's a breach or you suspect compromise, and use a unique password per site instead.
