When you choose One time password sent through Email as your Two-Factor Authentication (TFA) method in PAM360, an additional layer of security is added to your login process. Upon completing the first level of authentication using your regular credentials, PAM360 automatically generates a unique, random password and sends it to your registered email address. To proceed with the second level of authentication, you must retrieve this password from your email and enter it in the login interface. This one-time password is valid only for the current login session. If you log out and attempt to log in again, the previously sent password will no longer be valid. You will need to obtain a new password from your email to complete the authentication process.
Caution
Enable One-Time Password as the TFA and enforce it to the PAM360 users post configuring the mail server settings for the users from the PAM360 interface. Refer here for detailed instructions.
Users for whom TFA is enabled will have to authenticate twice successively. As explained here, the first level of authentication will be through the usual authentication i.e, users have to authenticate through PAM360's local authentication or Active Directory/LDAP/Microsoft Entra ID authentication.
Upon launching the PAM360 web interface with the One time password sent through Email authentication enabled:

Upon successful authentication, the user will be logged in to the PAM360 web interface.
