Hi @gustavo3
Welcome to the Auth0 Community!
Thank you for posting your question. The flow you see is correct as the result_url is a part of the Classic Universal Login Experiance. The redirect URI that the user is directed to after a successful password reset can come from multiple sources. This depends on whether you are using New Universal Login or Classic Universal Login ; whether you are generating a password change ticket directly via the Management API or sending a password change email via the Authentication API , from the login page, or other.
Everything about redirect during password change is described here → Why is password change/reset redirect not working? including Video Tutorial → https://www.youtube.com/watch?v=Jo3mLEDRKX8
Thanks
