What it is
Firebase Auth is Google's bundled identity service. Email + password, social, phone, anonymous, MFA. Generous free tier (50k MAUs). The standard pick for Firebase-stack apps; less of a fit for non-Firebase stacks because the lock-in is real.
Best for
- Firebase-stack apps using Firestore / Cloud Functions / FCM
- Mobile apps where Firebase SDK is the path of least resistance
- Cost-sensitive products at sub-50k MAU scale
When not to pick it
Skip Firebase Auth if you do not want to be on Firebase. The auth product is fine; the platform pull is real.
My take
Firebase Auth is good if you are already on Firebase. Outside that ecosystem the lock-in is not worth it. New non-Firebase projects rarely pick it.
