Password security guides
Short, practical guides on picking, testing, and generating passwords, grounded in NIST SP 800-63B and CISA recommendations instead of folklore. They're written by the team behind our free strong password generator, and every one gives you the answer up front, then the math behind it.

Rather just generate one?
Reading is optional. The Wi-Fi password generator makes router keys your devices will accept, the passphrase generator builds word-based passwords from the EFF wordlist, and the PIN generator handles phone and card codes. All of them run entirely in your browser, with zero network requests during generation.
