I've seen banks or insurers use DNI as user login.
- benhurmarcel 2y agoAll of them do I think. But from experience, they can change it for your account.
- SoftTalker 2y agoThe user login (hopefully) is not the internal primary key for the user. It should be unique at a given point in time, obviously, but certainly there are reasons it might need to change.
