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. It implements the challenge authentication mode.

For a more detailed insight see the code documentation Email Token.
