It would be great if you could track per login what personal information / identity was given in a structured manner (not just notes).

For example:
- which phone number was used
- which address was used
- which bank card was used
- and/or which identity profile was used

This would make it easy to track which logins need to be updated with new information in the case of:
- changing phone number
- moving to a new adress
- moving to a new bank (card/account)
