DOI Function for membership2 pro

We need to get a double opt in function for the membership 2, in order to add some new regulations in Germany.

In this topic, was mentioned a new feature "Enable the account verification" under the settings:

This is not enough to comply with the law? If there is a time stamp in the database which helps to proof the activation it should be fine.
