5.10.1. Email Token Configuration


Email Token configuration

For the email token to work, you have to first setup an SMTP server configuration and link it to the Email Token configuration at Config -> Tokens -> Email. The UI warns the user if one of these requirements is not fulfilled yet.

The Email OTP token creates a OTP value and sends this OTP value to the email address of the uses. The email can be triggered by authenticating with only the OTP PIN: First step

In the first step the user will enter his OTP PIN and the sending of the email is triggered. The user is denied access for now. Seconds step

In the second step, the user authenticates with the OTP PIN and the OTP value he received via email. The user is granted access if the OTP values match.

Alternatively, the user can authenticate with the transaction_id that was sent to him in the response during the first step and only use the OTP value. The transaction_id assures that the user already presented the first factor (OTP PIN) successfully. Configuration Parameters

OTP validity time

This is the time in seconds, for how long the sent OTP value is valid. If a user tries to authenticate with the sent OTP value after this time, authentication will fail.
