3. **`Optional`**\
   If you have previously registered for `Two-Factor Authentication(2FA)`, you may need to complete this step to log in. We strongly recommend setting up 2FA as it significantly enhances your security.

* We support two methods for 2FA
  * Using an Authenticator App (used after entering your password)
  * Using a Passkey (used instead of a password)
