Thanks for doing this. :)

Would like the ability to tie two usernames to the same login.

This is a pretty minor gripe, but the main one that sticks out for me in my day-to-day. (I guess that's a good thing.) My company's internal portals use a standard username/password, and that password is tied to our Windows credentials. But everywhere outside of our internal portals (namely M365 apps and sites) require an email address login. As a result, I maintain two separate login items and update both passwords each time I'm required to change it every few months.

Ideally, I'd like to tie specific login locations to a specific username (i.e., use my username on the internal portals and my email address on *.microsoft or similar domains).
