Two accounts - now needs two different passwords every time you login?

To add a little bit to this discussion: I think we're all anchoring on a solution and the discrepancy between 1P7 and 1P8 behavior. Instead, if we think of this as a UX problem, I think we can address the security needs and reduce the toil of having to enter multiple passwords.

I, too, agree with not using the same password across my personal and corporate accounts. However, I would propose that we can make the lives of those living in this world easier. Sure, hardware keys and Touch ID help, but my work laptop is hidden away from my main desk.

So instead, I would propose that y'all consider this to be a UX problem. The main issue I run into is that, once I enter a password to log in to one account, 1P8 thinks I'm done. It's not until I need a password from another account that I then realize I haven't logged in yet, and that UX is clunky. Instead, I would prefer the option to enter all of my main passwords at once when 1P launches for the first time. This UX pattern already exists: y'all do it when migrating from 7 to 8: there was a popup box that let me log in to both accounts before clicking "Done."

This, while clunkier than 1P7's approach, still solves for the "why are my credentials not showing up? oohhh, because I'm not logged into that other account yet."
