When you
understand how App Check will affect your users
and you're ready to proceed, you can enable App Check enforcement.
To enable enforcement for Realtime Database, Cloud Firestore, Cloud Storage, and Authentication (beta), follow
the instructions below. Once you enable enforcement for a product, all
unverified requests to that product will be rejected.
Open the
App Check
section of the Firebase console.
Expand the metrics view of the product for which you want to enable
enforcement.
Click
Enforce
and confirm your choice.
(Your project must be
upgraded to Firebase Authentication with Identity Platform
to enable enforcement for Authentication.)
Note that it can take up to 15 minutes after you enable enforcement for it to
take effect.
