Autofill APIs introduced in Android O just trying to help applications manage passwords and form data which was better than the previous versions of Android. As Google notes in his blog post, "Users can choose from autofill applications, similar to the way they choose Keyboard application. Autofill and secure application store user data, such as address, user name, and even passwords ". We had to wait a while until the application developers make full use of the API Auofill on Android O, but we should see the password manager is much more capable in the future.
