Unable to authenticate face after v1.3 update

Last updated September 26th, 2023


  • Knox Authentication Manager app v1.3


If device users previously registered their accounts with face sign-in on Knox Authentication Manager v1.2, then upgraded to v1.3 after registration, they would no longer be able to authenticate using the same face sign-in credentials.


To resolve this issue, a device user must manually sign in to the Knox Authentication Manager app. On the failure prompt, they must tap Sign in.

face ID fail

Then, on the Knox Authentication Manager home screen, they must tap the menu button, then tap Re-register face.

Users registering face sign-in for the first time on v1.3 will not experience this issue.
