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.
Common problems and how to solve them - lost phone, cannot login, etc.
