MacBook password rejected when adding Touch ID fingerprint

Hi everyone,

I'm trying to add a fingerprint in System Settings → Touch ID & Password. The prompt says "Enter the password for 'Robin' to add a fingerprint," but my password is rejected there. The same password unlocks my MacBook at the login screen and after sleep without any problem.

What I've tried so far:

Switched the keyboard input to English and checked that Caps Lock is off

Retyped the password slowly several times

Restarted the Mac

Has anyone seen the correct login password rejected only in the Touch ID enrollment prompt? Is there a fix other than resetting the password or reinstalling macOS?

Thanks in advance.

If that password unlocks the Mac, the Touch ID box is usually failing on the keychain copy, not because you forgot it. Quit anything that remaps keys, like Karabiner, and try again. In the password box, use the menu-bar keyboard menu and switch to ABC or U.S. You can also open Keyboard Viewer from that menu and click the password in, so you can see that every character is the one you expect. If it still rejects it, change the login password to the same password. System Settings > Users & Groups > your user > Change Password. That isn't a reset and you don't reinstall. It rewrites the login keychain, which is what the fingerprint setup is checking. Restart, then add the fingerprint.
