cancelled by another authentication

Hi when i try to add a fingerprint in the touch id on my MacBook pro. i keep getting the error message "cancelled by another authentication" even when i entered the password correctly. i have tried to rebook and everything and still not able to add a fingerprint and enable touch id feature. thanks

This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum.

Experiencing the same issue here. Trying to add my fingerprint (via System Preferences) so I can use Touch ID on my brand new MBP running macOS Sierra 10.12.1 but it's not letting me. Upon entering my administrator password (which is 100% correct), I am getting this alert: "Canceled by another authentication".  Not allowed to proceed from there.  I had bypassed recording my fingerprint during the initial setup process. Please help.

I got on the phone with Apple Support and the issue was resolved. We first restarted my MBP in Safe Mode but the issue continued there. We also created a new account, also in Safe Mode, but were able to record a fingerprint under that account.  Finally, the support engineer asked that I rebuild my keychain (Finder/Go+shift key (or was it Control key? --- sorry, can't remember)/Library/Keychains). Then dragged the contents of Keychains folder to trash. After restarting the machine I was at last able to record my fingerprint under the right account.

It worked.

修复此问题的方法：

1.打开Finder，在顶部菜单栏中找到“前往”，点击

2.按住option，会多一个“资源库”选项，点击

3.找到文件keychain，删除之

4.重启Mac，会要求您重设keychain等

5.设置touch id，成功

I translated your solution into Chinese.

Thx a lot.

I had a same situation, and I was able to work Touch ID by erasing Keychain too.

Below is a solution procedure in Japanese. Thank you very much.

Touch IDで指纹を设定しようとすると "Canceled by another authentication" というメッセージが表示される场合。

キーチェーンのフォルダの中身を全部消去し、（Finder/上部メニューの「移动」/フォルダへ移动/「~/Library」と入力/Keychain）コンピュータを再起动し、Touch IDを再设定して治りました。

As others have mentioned, there is an easy fix for this problem. The Touch ID problem is related to Keychain. Open Finder. Click Go once so the dropdown menu appears. Hold down the Option key. You will see a Library folder appear in the list under the Go tab. Open library. Drag Keychains folder into the trash. You will have to re-enter all keychain passwords, but the Touch ID will work.

I followed the steps but stil not working. I am unable to select the choices for Use touch ID for: they are greyed out.

If you recently changed your password...  

Try changing your keychain password (Keychain Access; select login; Edit menu click Change Password for Keychain "login".  Then try adding a Touch ID finger again.
