Hopsworks supports two factor authentication for enhanced protection. If your administrator has enabled 2 factor authentication, then during registration opt-in for it.
You should have a one-time password generator installed at your
smartphone, such as Google Authenticator. After you have clicked
the Register
button, scan with your smartphone the QR code
presented to you. Next time you login again, it will prompt you both
for your password and for the six-digits one-time password generated by the
application at your smartphone.
