I want to know:

• What is the changes that occurred after the new upgrade has been released, and how can we benefit from it?
• Should we now choose to work with only one of Firebase Authentication with Identity Platform and GCP Identity Platform?
• What changes should be implemented if I want to migrate from GCP Identity Platform into Firebase Authentication with Identity Platform?

>Solution :

1. One of my favorite features that are implemented is that we are able to register blocking functions. If you read the docs, you’ll all the benefits.

2. It’s up to you to decide, but in my opinion, I would prefer to use the newest solution.

3. As far as I noticed, none.

Once you migrate, you’ll see in the Firebase console in the Authentication section on the top of the page, the following text:

Authentication with Identity Platform

And to answer your question:

What is the difference between Identity Platform and Firebase Authentication with Identity Platform?

The real benefit is that you can use all the other Firebase products.

Edit:

Besides the blocking functions, there are other new features present, that weren’t before:

• Multi-factor authentication
• Sign in with OIDC
• Sign in with SAML
• Multi-tenancy
• IAP integration
