We would like to authenticate the user with Auth0 using our custom login form (with username and password). And this seem to be the correct resource: https://auth0.com/docs/api/authentication#resource-owner-password However, I get a response of: { “error”: “access_denied”, “error_description”: “…

You’re sending the parameters as query parameters and as mentioned at ( Authentication API Explorer ) the expectation of that endpoint is that the parameters are sent in the request body using application/x-www-form-urlencoded encoding.
