“Why wouldn’t I use verification? I’ve got nothing to hide”.

This. This is why you do not submit willingly, regardless of what you have to hide. Fascism doesn’t give a shit if you’re innocent.

Using Microsoft teams at work, it keeps on asking me record a voice sample and selfy so it can identify me in meeting , yeah no thanks

And then your coworkers think you’re IT challenged because you don’t even know how to do the simplest things. (true story)

My company just mandatorily implemented “Windows Hello”

No one seems to be able to tell me why the information from Microsoft says the fingerprint and face scans are both “local only” and may take 24 hours to sync after initial setup. Where are they syncing to?
(I opted for the ‘pin’ method instead of surrendering my biometrics.)

PIN is the best way to go there. It only works on that one machine, although you can technically set the same PIN again on another computer.

I believe the typical intent is as follows:

It is now possible to brute force things that were previously considered “complex” passwords in a semi-reasonable amount of time.

This necessitates longer and more complex passwords

People can’t remember those so they have a tendency to write them down or do other relatively insecure things with them.

Forgotten passwords can generate a lot of helpdesk calls and are also an attack vector

If we insist on really complex passwords that are too long to reasonably brute force with current technology, we need a way for users to log in that’s not going to make 3 and 4 a major issue.

If the simpler PIN method is locked to a per machine basis, it matters a lot less if the PIN is compromised because you also need physical access to the computer or the PIN is useless.

This should, in theory, allow workplaces to set requirements for really complex passwords that only need to be reset once a year or so, without breaking helpdesk, inconveniencing users, or leaving gaping security holes.

Whether or not that all happens depends on the workplace, but that’s the general thought process in most of the places I’ve worked where a modicum of sense prevails

…. Oh!

You just explained a question I had.
I couldn’t figure out why a pin was considered more secure.

In my reasoning: How is a PIN (potentially numeric only), changed 1x a year, safer than a password (3 of 4: Alpha, Mixed case, numeric, special chars), changed 4x a year.

The answer, as you explained, is scope of trust. Machine only vs tenant-wide. That makes sense.
