Today on Apple’s developer site, the company announced the release of new resources for password manager apps:

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.

The open source project can be accessed on GitHub.

Apple has continually deepened its investment in the area of password management with iCloud Keychain upgrades in recent years and new APIs for third-party apps. Today’s announcement takes things a step further down the path of openness and collaboration, enabling apps to share important site-specific information with one another so that users have the best, most secure experience possible no matter their choice of password manager.
