iMac keyboard fingerprint not working, set it up and fingerprint works for 1-2 days and then have to enter password. Any ideas?

• If you still have to enter your password: For security, you need to enter your password when you start your Mac. Sometimes you need to enter your password to continue using Touch ID. For example, users must re-enter their password every 48 hours and after five incorrect fingerprint attempts.
