Weak, reused passwords are the single most common cause of account breaches. Our Password Generator creates strong, unpredictable passwords in three styles — fully random, memorable passphrase, and pronounceable — right inside your browser. It never sends anything to a server, so the password you generate is seen by no one but you.
A live strength meter and entropy readout show you exactly how hard each password is to crack, so you can dial in the right length and character mix for logins, Wi-Fi, encryption keys, or anything else that needs protecting.
Create ultra-secure passwords with full control.

Passwords are secure-blurred by default. Hover or tap to reveal.
History is empty. Generate some passwords!
Passwords are built from the browser's secure random source, not a predictable formula.
Generation is 100% client-side. No password is ever transmitted, logged, or stored.
See real-time entropy and a crack-time estimate so you never settle for a weak password.
No. Everything is generated locally in your browser. Once you close or refresh the page, the password is gone unless you saved it yourself.
Length and unpredictability. A longer password drawn from a large character set has higher entropy, which is what the strength meter measures.
A passphrase strings several random words together. It is long and easy to remember while still being very hard to guess.
