W11 TPM only works for 1-3 reboots

Hi ZyroBlue, thanks for reaching out to us. I'm sorry to hear of the troubles you've been encountering with Enhanced Windows Hello after a few reboots.

It works nicely, but only for one to three reboots, after that I have to type in my password again (after which my Hello PIN is asked).

When you are in this state, after you enter your account password, and subsequently your Windows Hello PIN, does restarting 1Password 8 after fully quitting the app from the icon in the system notification tray, resume this functionality?

We're aware of some customers who have been experiencing similar issues with Enhanced Windows Hello and one thing that Microsoft had mentioned could be a factor in invalidating the TPM state is using the fast startup option on your computer. You can see if this is the case by disabling the feature following the steps found here: Disable Fast Startup

If this continues to be an issue, can you send a 1Password diagnostics report via email to support+windows@1Password.com so we can help to investigate? Please do not post these details in the forums.

Can you also include a link to this thread in your email, along with your forum handle so that we can "connect the dots" when we see your report in our inbox. Thank you!
