About
Passwords, random strings, hashes, and 2FA are computed in the browser. Secrets and hashed text are not uploaded. These tools generate and check; they do not store a password vault or claim to be an official authenticator.
How to pick a tool
Use the password generator for a new password, strength check for an existing one, random strings for tokens, hashes for digests, and 2FA/TOTP for login codes.
Safety notes
Local generation is not “perfectly safe”: length, character set, and reuse are still your choices. Paste only your own 2FA secret, then clear the box.
How secrets are handled
Passwords, random strings, hash input, and TOTP secrets stay on this page. Save the result in your own password manager or authenticator immediately. Do not send secrets over chat. This site has no cloud vault and cannot recover the last generated password.
