Problem with 2FA for two different subscriptions with the same Ext

[ciits]

Hi

I manage a couple of subscriptions and have issues with 2FA.
scenario

Sub 1: Ext 100@abc.com
Sub 2: Ext 100@xyz.com
2FA authenticator:- Microsoft Authenticator

when I enable 2FA for [email protected] , this overwrite the 2FA for [email protected] .
and when enable 2FA for [email protected] , this overwrite 2FA for [email protected].

The only solutions are to use different authenticators or different extensions.

is it possible to use the same authenticator for 2FA for multiple subscriptions with the same ext (100 ) ???

Is it the same email address used for both? And Microsoft Authenticator?
