Using OTP based on last login

Hello! I would like to know if it is possible in privacyidea to use 2FA with OTP only when a certain time has passed since the last login. Privacyidea is currently used integrated into the authentication process of simplesamlphp

For security reasons this is not possible.

I personally think this is a very bad idea!

However, this could be part of a bigger concept, which we think of as “pre-authentication”.
