Option: Current/new session kicks out previous/last session

Thanks, will test it asap.

This feature can help increase security in a practical way:

One way of ensuring that a user does not share his/her password/account with anyone else, could be to add a setting that actually sends out a temporary link that must be used to be allowed to kick out the other session. That will ensure that only that user can kick him/herself out. The link will be sent to that user's email, and when used followed by a successful login, then the previous session is replaced with the new one.

One particularly practical use case for the above is sites that require paid subscriptions to access the site or certain parts of it. In those cases, it is a concern to prevent people sharing their account.

Obviously this does not make a fool proof solution, but will help keep such "abuse" of terms to a "minimum" without significant cost.

Ah, and further on that - since many of us use 2-3 computers - home, laptop, work, etc., that module should still allow a setting of x active sessions per user. Each requiring such a one-time link to "register it".

Would be perfect if admins could set one such limit per role, using the highest number for users that are members of serveral roles.

The session_limit should then only delete the oldest session for that user once that threshold is reached.

I believe this will be a very useful module for a lot of sites.
Could even help "sell"/promote Drupal by itself.
