If you enter the same info twice, including the salt, you will get the same password output. The password is generated using a random seed, based on your salt.

This way you can have a unique password for each device and domain you use. So, if your password is breached, you can just create a new salt for that login - and voila — your breached password is updated — and an attacker can't use your cracked password to unlock another digital realm.

1. You will have a unique password for everything.
2. You never have to write any passwords down.
