Integrate a Password Management App with Password AutoFill If you are developing a password management app, create AutoFill Credential Provider Extensions to surface credentials from your app in Password Autofill and pull your app’s password data into the Password AutoFill workflow. When your app integrates with Password AutoFill, users don’t have to copy and paste credentials. Instead, they can use password data stored in your app easily because the data will be offered to the user to fill in compatible user name and password fields. To integrate a password app with Password AutoFill, use in the AuthenticationServices framework.
