How secure is the new Face Unlock

I’ve just updated to the latest release on Android. I notice that the update included being able to access Chip via Face Unlock. My question is this: How secure is this considering I did not need to set this up as an option within Chip itself. I presume it looks at my Secure Login details for my Samsung A50, as I’ve not needed to setup a new Face ID via Chip.

I’m shocked that this has not been turned off by default so it lets the User/Customer of Chip set it up within their Profile Settings?

It would only be set up if your phone is already set up. How would it know your face otherwise?

If you already have face unlock- I dont see any problems here.
