The password auto-fill experience is much better on Android. Starting with Android 11, virtual keyboards and other input-method editors (IMEs) will allow autofill suggestions to be displayed inline as a suggestion bar.
That way, you don’t have to wait for the implementation of the current dropdown menu, which doesn’t really provide a seamless experience and may be out of place in some cases.
As you probably know, autofill suggestions usually contain sensitive information such as personal data and credit card details. Keeping privacy in mind, Android hides suggestions from the keyboard until the user taps on it.
According to the official documentation of Android 11 beta, developers of both IME and Password Manager have to update their app to support this feature. If the IME or password manager does not support inline autofill then the old implementation (Android 10 and below) will kick in.
As Android Police points out, the interface of this new keyboard-integrated password autofill mechanism may look similar to that recently added by Google Chrome. However, we will have to wait to know if it will exist as a separate component (as seen below) or will appear in the text predictions.
We can expect the popular keyboard app and a password manager to include changes over time for the launch of Android 11, which is expected on 8 September. You can learn more about inline Autofill’s workflow in Google’s official document. The page also has instructions to help developers configure inline autofill for their apps.
