I’ll share what I researched about Auth0 Change Password API specifications.

Background: Want to Send Password Reset Email via Auth0

To fulfill the requirement “Want to send password reset email via Auth0 API,” I used the Change Password API.

• POST /dbconnections/change_password | Authentication API Explorer

Change Password API Research Results

Gmail Alias Feature Not Supported

Email addresses using Gmail’s alias feature (addresses containing +) do not trigger email sending when making API requests.

API Response Message is Always the Same

Regardless of whether the email address exists in the Auth0 database or not, the Auth0 API response always returns the same message.

This appears to be a specification to prevent clients from knowing whether the email address is stored in the database based on the API response.

• Reference: requestChangePasswordEmail returns empty response in case of success and error, I can no differentiate these cases - Auth0 Community

That’s all from wanting to understand Auth0’s password reset email API from the Gemba.
