MFA: I-MATH & DM3L - text based setup via SSH

Text base alternative MFA setup option via SSH

If you have no clue what SSH is - skip this section, you won't miss anything.

The second factor is checked by SSH connections. If no second factor is configured yet, you will have a chance to configure one.

Note 1: You can select any text with a mouse and copy to the clipboard with Ctrl+Shift+C.

Note 2: Press Ctrl+C to cancel the authentication at any step.

  1. Recovery codes:

  2. TOTP: copy the secret to your authenticator (such as KeePassXC)

  3. Email: the email assigned to your account will be used

If second factor is already configured, you can use a code from any method. Type email to request an email code - an email is sent automatically only when it is the only method. mfa-ssh-challenge.png

Entering an invalid code does not break the authentication process: you will be given another chance to enter a correct code.
