That sounds interesting, what if i already have a database with users and hashed passwords ( i.e. we got an application using meteor ) ?

You have a couple of options here:

• You can import your users (including password hashes).
  • This option requires some initial migrating development time, but after it is completed there is very little you will have to manage, and you can always export later if needed.

OR

• You can point auth0 to your existing database.
  • This requires a paid subscription, and you will have to maintain your database infrastructure and integration, but you wont need to migrate your users and hashes.

How do i setup auth0 to check the passwords using the same encryption on the email ( i believe meteor is sha256 )

This will depend on whether you import your users (yes, we support SHA256) or integrate with a custom database. Here are resources for the two different options.

what if a user tries to login with Google or Facebook but they’re already registered?

You can set up account linking. So a verified email from either social provider will be linked.

Also, if the user decides to sign up using email / password ( as opposed to social logins ) can i only allow the login to happen after confirming the email?

You can force email verification in a rule. Essentially they can login, then you can deny access to your app until they are verified. This is a common flow.
