Apple has created a new open source project to help developers of password managers collaborate to create strong passwords that are compatible with popular websites. The Password Manager Resources open source project allows you to integrate website-specific requirements used by the iCloud Keychain password manager to generate strong, unique passwords. The project also contains collections of websites known to share a sign-in system, links to websites’ pages where users change passwords, and more.
There are quite a few password manager apps out there these days, so it’ll be interesting to see how this will be utilized.
