If you're on Android 8 or above (yes, I know most people aren't) there's support for password managers filling passwords in almost any app. Some apps aren't well built and don't support it. As far as I can tell, it's not something the developer has to explicitly enable support for though.
Anyways, I use the Bitwarden app on my S8 (and previously HTC 10) and it works great. I tap a password field, Android asks me if I want to fill the password, I unlock my "vault" with my fingerprint, and tap the right account for that app. It's pretty easy.
LastPass and Bitwarden also can hook into accessibility features on Android 7, to enable most of the same features, but since it's not part of Android and baked in it doesn't work quite as well.
Hey, thanks for telling. I've been using 1pass on android since a long time ago, and autofilling username and password is a real hassle. In the past the only way to do the autofill was to use the 1password keyboard, which is inconvenient for me to change keyboard every time filling a password. But I just try the new autofill feature on the Android 8, and it works like a charm. It supports autofill on native apps and webpage via Google Chrome as well.
