Personally I have the following situation:
I have an Active Directory account and on top of that, different applications use different 2FA step-ups (two different TOTPs).
If I duplicate the full login record, I would have to manage both if I change the AD password and 1P would tell me that I have a reused password.
It would be great to have one shared master login (AD) with the username/password and 2 other ones, linked to the master for both applications with different TOTP.
Anyone else in such a situation or similar where this could help?
