Migrating between Firebase Auth and Auth0



I’m using Firebase Auth in an app.

I’d like to know if it’s possible to migrate to Auth0 without friction for my users. Something like exporting there, importing here.

Also, would I be able to migrate back to Firebase Auth in the future?

Thanks in advance.


A normal user export from Firebase, and import into Auth0 using the extension or API v2 would require users to reset their passwords. As a workaround, you could try something along the following lines:

  1. Set up a custom database connection in Auth0
  2. Enable the Import users to Auth0 migration]2. This is a seamless migration, which doesn’t require users to reset their passwords.
  3. Instead of connecting to a database, your login and Get User scripts can call the Firebase REST API.
