One of the best password management tools in its category, created by Apple is known as iCloud Keychain.

The company seems ready for the next big step in the password management space, having released a new open sourcecalled Password Manager Resources.
Apple said it wants developers to take advantage of what the company already knows and suggest more improvements that will benefit password management tools in general. The project is available on GitHub repo and includes resources on the site-specific requirements that iCloud Keychain uses to generate strong and unique passwords.
Developers can also find details about sites that share a common login system, as well as links to pages where users change passwords.
According to the company's logic, sharing resources can bring more improvements with less effort, as opposed to individual work. It can also encourage sites to adopt common standards for password management and improve compatibility with different password managers.
The project comes at a time when Apple already has a program to store passwords across devices. Also last year, Apple announced the “Sign-in with Apple” SSO button, which is an alternative to the login options from Google and Facebook.
As Apple announced back then, its alternative login follows different processes and places greater emphasis on privacy, ensuring that third‑party sites do not collect a lot of user data.
