Master Password Manager Helper

About Master Password Manager Helper Android App

This app generates a different password per website using your master password. Use your master password to recreate any password, at any time. Passwords are NOT stored anywhere.

Tech note - This stateless password maker uses pbkdf2-hmac-sha512 and utf-8 encoding throughout (e.g. Japanese characters supported). See below for precise output construction.

This can help when used with a Password Manager, if:

1. You use a password manager and don't trust its online storage of your passwords.

2. You have multiple devices and often find a password you need isn't saved on one of them.

3. You want to use a different password for each website.

PassMgr Helper does NOT store your passwords anywhere! It re-creates them securely from a combination of the website url (any text will also work) and your master password. You only need one master password.


Output construction:
charset-encode( pbkdf2-hmac-sha512( master-pass-utf8, iterations, sha256-raw( output-length-big-endian-16bit + charset-size-big-endian-16bit + salt-utf8-num-bytes-big-endian-16bit + iterations-big-endian-32bit + salt-utf8 + url-utf8 ) ) )
