I have a macbook air from 2018. The problem is that whenever I want to add a fingerprint, the message 'Fingerprint limit reached. To add a new fingerprint, remove a fingerprint from any account on this Mac.' appears. I have not a single fingerprint added on this mac and there aren't any other accounts except for mine. What can I do? (I have done all the updates).

Take care & good luck!🌞🎣
"..On MacBook Air models introduced in 2018 and later, the
Touch ID button is on the right side of the function keys.."
Otherwise the Apple Support article [and others] are spot on.

Only issues noted for MacBook Pro and MacBook Air with Touch ID
(failure) was the matter of dirty scans; or a need to try again. These
are covered most all. ~ Where did the Chip come in? Didn't see it.
This should also work with MB/Air:

Are You sure this method is suitable for macbook air 2018? I've seen such guides online and they were dedicated for macbooks pro. Furthermore, they included warnings that devices with Apple T2 chip are not suitable for this.
I have searched high and low for a resolution to my Touch ID no longer working (stopped working when Covid hit). I have searched, begged, read, and tried any and all tricks I possibly can too get it to work again. I have read that the "xartutil --erase-all" in Terminal wipes out the T2 Secure Enclave on the MacBook Pro 15" late 2018. I have also been told (by an Apple Support rep via chat) that the Touch ID only has "so many uses" before hit is rendered useless as all of the "slots" have been filled.
I don't know what to believe or do. I partitioned my drive and installed the developer beta hoping that THAT would fix it and no cigar. I know a ton of people who are STILL searching for a fix to this issue.
What are your thoughts on trying xartutil --erase-all?
Help!
