I have a ~1 year old Framework 13 running Windows 11. When I got it I set up the fingerprint login and it worked fine, but after a little while (weeks to months) it started working only some of the time, and then almost none of the time. I took some time off using it but earlier this year tried setting it up again and it worked great! For weeks/months and then it started working only some of the time, then rarely, etc. I just deleted and re-setup the finger and it works great again. For now.
Is this likely a hardware issue, or a windows thing, or is my finger just changing so much over the course of months that it stops being recognized? FWIW I’m an adult so my finger isn’t growing rapidly (AFAIK).
