Phone is locked and already at 60 min
This is a security feature of Android: it will occasionally ask for the password after being unlocked with a fingerprint (presumably in case someone steals your phone and cuts your finger off, or I don’t know why). That’s just how it works. Fingerprint is only a convenience, you really have to remember the password.

According to Google, your only option is to hard reset the phone and start it all over.

I would not be so worried about backups: nowadays most of your data is stored in the cloud. I don’t know about your situation specifically, but the only pieces of information that are not in the cloud on my phone are SMS and call history, which I don’t care about. Therefore, I would not hesitate to erase my phone.



Fine print: in case your disk is not encrypted and the bootloader is unlocked, it is pretty easy to extract all the information, but I assume, if you had bootloader unlocked, you would not be asking your question here.
