    2. Port: The port number. For example, 465.

    3. Authentication Required: By default, this option is set to OFF, keep the option in this state if your SMTP server does not require authorization.

      Set this option to ON, to specify the password required for the SMTP server authorization.

    4. Username: The username of an account that is used to send the authentication email messages. For example, noreply or noreply@company.com.

Authentication Flow

The authentication flow for the Mail sender is described in the following image.

A user wants to authenticate on an endpoint such as a laptop or a website with the Email OTP method. The following steps describe the authentication flow:

  1. When the authentication request is initiated, the endpoint contacts the Advanced Authentication server.

  2. The Advanced Authentication server validates the user’s credentials and gets an email address of the user from a repository.

  3. Advanced Authentication server sends the request to a configured mail server to send an email message with the content that includes a one-time password (OTP) for authentication.

  4. Mail server sends the message to the user's email address.

  5. Mail server sends the sent signal to the Advanced Authentication server.

  6. Advanced Authentication server sends a request to the user to specify an OTP on the endpoint.

  7. The user specifies the OTP from the email message. The Advanced Authentication server gets the OTP.

  8. Advanced Authentication server validates the authentication. The authentication is done or denied.

HTTPS protocol is used for the internal communication.
