Ricky Mondello over on the Safari team just recently shared a note about how Twitter is using the ./well-known/change-password spec. I just noticed that Twitter has adopted the Well-Known URL for Changing Passwords! Is anyone aware of other sites that have adopted it? Twitter's implementation: https://twitter.com/.well-known/change-password Github's: https://github.com/.well-known/change-password Specification :https://github.com/WICG/change-password-url Read full post. The feature completely passed me by but it is a neat idea: given a file in a well-known location, can the browser offer a UI to the user that allows them to quickly reset their password without having to navigate the sites complex UI.
