Client-side password management software helps improve both the security and usability of websites which require authentication. It improves security by reducing cross-site password reuse, and enhances usability by providing autofill functionality.
Sites currently lack a way to programmatically advertise where a user can change their password. By proposing a well-known URL for changing passwords, this specification enables password managers to help users change their passwords on sites which support it.
This specification depends on the Infra Standard. [INFRA]
This specification uses terminology from the Fetch, HTML, HTTP, and URL standards. [FETCH] [HTML] [HTTP-SEMANTICS] [URL]
3. Change Password URLs
A change password url of an origin is a URL that points to a resource that clients can use to discover where a user should go to update their password on origin.
Given an origin, clients generate a change password url by running these steps:
If origin is not a potentially trustworthy origin, return failure.
Assert: origin is a tuple origin.
Let url be a new
URLwith values set as follows:
« ".well-known", "change-password" ».
The change password url for origin
Servers should redirect HTTP requests for an origin’s change password url to the actual page on which users may change their password by returning a response with a redirect status and Location header. [FETCH] [HTTP-SEMANTICS] Clients must handle such redirects when requesting a change password url.
If necessary, servers may respond with an HTML document containing an
http-equiv pragma directive in the refresh state. [HTML] Clients should handle such redirects when requesting a change password url.
Servers must not locate the actual change password page at the change password url, per RFC5785 §1.1 Appropriate Use of Well-Known URIs. Clients must handle ok status responses when requesting a change password url.
4. IANA considerations
change-password well-known URI
This document defines the “
This registration will be submitted to the IESG for review, approval, and registration with IANA using the template defined in [WELL-KNOWN] as follows:
- URI suffix
- Change controller
- Specification document(s)
This document is the relevant specification. (See §3 Change Password URLs)
