how to debug

[snoblenet]

I am on Mac OS X Catalina. I have a password in 1Password consisting entirely of ASCII letters, numbers and punctuation. I copy it, but my cursor in the password field for Microsoft Teams for Mac OS X, and click Force Paste in my dock. I can see the password field is populated by a string of obscured characters so I click Sign-in. Microsoft Teams rejects the sign-in attempt, saying my password is incorrect.

When I repeat the experiment by typing my password manually I can sign in.

Is there some way I can check that the password being entered is the password I expect?

I just used Force Paste on a non-password field and confirmed it is pasting the correct password. So the issue must be with Teams somehow.
