user_metadata

Hi nidhaldring,
Thank you for posting on Auth0 community!

To answer your questions:

You can use the Auth0’s Authentication API and Management API v2 for both of those things.

1. check if a user exists with the given email and password - GET user by user id
   GET users by email

2. if it exists i want to get all of his details including user_metadata, app_metadata, and roles -

• user_metadata - You can also use the GET /userinfo endpoint to get a user’s user_metadata , however you must first write a Rule to copy user_metadata properties to the ID Token.

• app_metadata - Use the following Management API endpoints to view, create, update, and delete the user_metadata and app_metadata fields.

• role - Auth0 Management API v2

Hope this helps answer your questions!

Thanks,

thanks but as for 1 is there a way to use BOTH password and email to check if a user exists from a backend application ?
i’m reading the documentation now but it’s a bit unclear when it comes to this.
thanks again

Hi nidhaldring,

No, there is no way to check if a user exists by their password (for security and privacy reasons). Can you please elaborate on what your use case for this is? We may be able to provide a work around depending on your needs.

Thanks!
