Time-based one-time passwords (TOTP) are used for 2-factor authentication. Normally user enters login and password, then user should enter 6 digit one-time password, which is generated by a dedicated application. This one-time password is generated from the current time (and valid for 30 seconds) and a secret key provided by an authenticating web site (usually as a QR code).
To add a one-time password:
- Start editing a card.
- Press Add another field button.
- Select One-time password.
- Then input a provided secret key or scan a QR code by pressing the QR code icon next to the field.
- Save the changes.
