MyPassGen
About MyPassGen
A browser-local encryption toolkit for people who want a password generator and privacy tools without creating an account.
MyPassGen runs on mypassgen.com. It is built for developers, operators, support teams, and anyone who needs to generate a password, check strength, strip tracking parameters, share a one-time secret, or encrypt a file — without signing up first.
Sensitive work stays in the browser by default. There is no user account and no password vault. A one-time secret is the only path that briefly hands ciphertext to the server. The decryption key lives in the URL fragment after # and is not sent with the HTTP request.
The only algorithm is AES-256-GCM. Computation uses the Web Crypto API. Read the security notes or the FAQ if you want the same facts in one place.
