Two-Factor Authentication via TAN List

Prerequisite

For TAN lists no prerequisites are required!

Instructions to Rollout the TAN token

  1. Open menu entry "Enroll Token" of the SIM-MFA web portal (Fig. 1).

  2. Select token type "TAN: TANs printed on a sheet of paper.") from the drop-down menu in the SIM-MFA web portal (Fig. 1).

  3. TAN settings (Fig. 1)

    • "Description": optional (may be useful to identify a token in the list of tokens, see menu entry "All Tokens")
  4. Roll out the new token via button "Enroll Token" ("Token ausrollen") (Fig. 1).

  5. The SIM-MFA portal has successfully rolled out the token, shows its serial number PITN######## and has created a printable TAN list (Fig. 2).

    Print TAN list (Fig. 2)

    For security reasons, please do not save the TAN list on your computer or any other filesystem! Instead, print the list on paper and keep it in a safe place!

Done!

Now, the TANs can be used as one-time passwords (OTP). We recommend to remove used OTPs from the list!
