Email-Based OTP

SmartSign supports OTP delivery by email

SmartSign supports the email-based delivery of single-use OTP codes to the user's email address. This can be a convenient way to allow users access to a system in the event of a lost/stolen token.

Email OTP codes can be used to grant short term access when deploying physical tokens may be undesirable.

You needn't worry that our email-based authentication is less secure though; we use the same industry-standard algorithms as used by our smartphone app.
