I've been using Google Identity Toolkit for my project for more than 2 years now and quite satisfied with it. Of late, I have been facing issues with it though. Last month the AOL accounts stopped working suddenly. I reported it on Stack Overflow (SO) and it was addressed by someone from the Identity Toolkit team. Right now password reset is not working for my project (which as a GAE for Java backend). I have posted the issue again on SO and its awaiting resolution.
It is becoming untenable to continue using this product without proper support. Therefore, I started the process to migrate off to Firebase. However, Firebase Auth has its own set of issues and I'm quite disappointed with it. I have sent my feedback to Firebase support already.
Now I'm considering another service from a Google competitor for authentication. Therefore, I would like to know whether it's possible to export all the users (I have 50K+ users) out of Google Identity Toolkit and take it somewhere else. For email/password based accounts, would I get the "hashed" passwords as well?
Thanks.
