Force users to receive new PIN code


We are using pro app internally in my company with email white list. I’d like to make sure that retired employees are not using app.
Deleting from the white list is the best, but deleting can sometimes be so late. My idea is to force all users to receive PIN code on company email address periodically. Is that possible?


I’m not aware of a way to force new pins. My best advice would be to develope a procedure to always delete from whitelist once the the employee retires.
