After restarting Windows, Window Hello is no longer available to unlock 1Password

Hello @k3vlar,

Thanks for your message. It sounds like you may need to enable the Use the Trusted Platform Module with Windows Hello. The behaviour you describe is expected if this option is disabled or your device does not have a hardware Trusted Platform Module (TPM) 2.0. You can learn more about this setting here: Windows Hello - Manage your settings

I do not have my 1Password password memorized, so this is a very annoying bug that is preventing me from using the application effectively.

If you are able to enable the TPM setting this will help, but until you memorize your account password, I wanted to remind that we provide Emergency Kits so you can store all of your account credentials in a safe place. I'd recommend saving and printing a copy of your Emergency Kit so you can record your account password in the space provided. That way you'll always have access to your account. If you lose your Secret Key or account password, we cannot restore it for you or help you recover your account.
