Smart Password Generator от Elementus

How does it work?
This app generates strong, unique passwords for every website using a master password. All processing is done in your browser—no server and internet connection needed.

Algorithm:

hex = SHA256(masterPassword + domain)
base64 = hex_to_base64(hex)
password = first_16_characters(base64)


Is it safe?
If you use a strong master password or passphrase, then yes. Diceware is a recommended method to choose a strong passphrase. If you check “remember” for the master password, it has a risk of being compromised by malware.
