Two-factor authentication

NSC / Support / Two-factor authentication

Some NSC clusters require a second factor (i.e not just a password) when logging in. On these pages we describe how to use those clusters.

In this documentation, we use “2FA” as an abbreviation for “two-factor authentication”.

The 2FA method we use is TOTP. To log in, you need to enter your password and then a 6-digit code generated by an app on your phone.

If you have lost your phone, uninstalled the app or your TOTP codes are no longer working, please read the troubleshooting page.
