Auth0 Failed Signup Error Indicates The User Already Exists After Dashboard Deletion

An Auth0 failed signup (fs) error occurs when a user attempts to sign up after an administrator deletes the user from the Auth0 Dashboard. This happens because the user record remains in the Auth0 Database connection. Resolve this issue by using the Auth0 Management API to delete the user by email address. The Auth0 logs display the following error description:

The user already exists.

• Auth0 Database connections

The user record still exists within the Auth0 Database connection even though an administrator deleted the user via the Auth0 Dashboard.

How is the user deleted from the Auth0 Database connection?

Delete the user directly from the database connection by making a request to the Auth0 Management API delete-users-by-email endpoint.

1. Navigate to the Auth0 Management API delete-users-by-email endpoint.
2. Execute the API request using the connection ID and the target user's email address.
