   *Enroll an EMail token*

When enrolling an EMail token, you only need to specify the email address of
the user.

The EMail token is a challenge response token. I.e. when using the OTP PIN in
the first authentication request, the sending of the EMail will be triggered
and in a second authentication request the OTP value from the EMail needs to be
presented.

For a more detailed insight see the code documentation :ref:`code_email_token`.
