Generate strong random passwords or memorable passphrases. Cryptographically random, never transmitted, no sign-up required.
This password never leaves your browser. We don't log, store, or transmit it. View source if you want to verify.
Free, forever, no sign-up. Runs entirely in your browser - nothing is uploaded. Part of techtuate, a growing collection of little tools that just work.
Passwords use crypto.getRandomValues - the same CSPRNG your browser uses for TLS. Passphrases draw from a 2048-word list, giving ~11 bits of entropy per word. A 4-word passphrase gives ~44 bits; a 6-word gives ~66 bits. Both are dramatically stronger than a memorable human-chosen password.
