## Description

Passcode generates a site-specific unique password for all your services.

It takes the domain of the service (e.g., twitter, apple, or linkedin) and your master password (keep this a secret) and using an algorithm (SHA256), generates a new password for you to use for that service.

Once you've generated the new password for your service (and changed your password on the website), you can log in by generating the password again.

By crypographically combining a "master password" with the domain of the service you are requesting a password for, it ensures that no two services have the same password from you, but with the convenience of only having to remember one!
