I upgraded my HP Envy-15t Laptop to Windows 10 recently and the fingerprint login feature was working just fine for over 3 months.
Today, I tried to add another finger print for my spouse using the sign-in options under Accounts setup. The fingerprint option did not work for her. Then I tried removing all fingerprints and set up my fingerprint again.
Now, the fingerprint does not work at all. It comes up with 'authentication failed - please try again' message. I really liked the fingerprint option to login and want to restore that feature back. Please help.
