I'm pretty frequently (maybe at least once a week) seeing the yellow exclamation point on my personal account's profile on the login screen and getting prompted to enter a two-factor auth code. This isn't the device's owner; it's enterprise-enrolled and my corp account owns it. I think that this has all been happening on this one device.

This evening, I:

1. Saw the exclamation point and signed in: https://feedback.corp.google.com/product/208/neutron?lView=rd&lReport=10693273894

2. Signed out, saw the exclamation point a second time, and signed in again: https://feedback.corp.google.com/product/208/neutron?lView=rd&lReport=10693388446

3. Signed out again, *didn't* see the exclamation point this time, and signed back in: https://feedback.corp.google.com/product/208/neutron?lView=rd&lReport=10693430066

There's an earlier feedback report from when I saw something similar a few months ago at https://feedback.corp.google.com/product/208/neutron?lView=rd&lReport=6874319091.

No idea if it's related, or how it would be, but I noticed that the feedback prompt pre-filled my username as "dan.erat" for 1) and 3) but "danerat" for 2). Dunno what's up with that.
