All the signups are held in a map which gets deleted every time the app restarts. The app listens on port 62222, ie localhost:62222
There are four pages:

- /signup
- /qrcode
- /validate
/
The home page displayes a standard login page with a signup button. The signup button takes you to /signup
/signup
The signup page allows you to create a new user by entering an email address and a password. The email's validity isn't checked, but the password is
checked against the HaveIBeenPwned breached passwords list. Successful signup will take you to the /qrcode page.
/qrcode
The qrcode page displays the QRCode used in your authenticator app. The QRCode is created using the domain, your email and a secret key. After
scanning the code you go to the /validate page.
/validate
The validate page allows you to enter the time based code from the authenticator app and check whether it is valid or not.
