Using Email OTP

Authenticating with LoginTC

Here is an example of Email OTP authentication with Windows Logon:

The user selects Email and then clicks Email me a passcode. An email will be sent to the user containing a 6-digit One-Time Passcode. Entering the correct OTP will result in a successful authentication.

Email OTP also works with Authentication Mode Challenge Interactive on the LoginTC RADIUS Server:

When prompted, the user enters email. An email will be sent to the user containing a 6-digit One-Time Passcode. Entering the correct OTP will result in a successful authentication.
