unlock options grayed out

I installed an app which required me to set a pin for tablet unlock. Brain froze and don't remember which program. Thought it might be banking app. Looking at credential storage nothing rings a bell.
Minor annoyance, just wanted to play with face unlock.

Depending on the permissions, you won't be able to use face unlock.  My Department of Energy App requires similar pin access.  The opportunity to use face unlock has been grayed out also.
