The Verge: The latest Android devices now let you log into apps without requiring a password

Here’s a good reason to update to your latest version of Google Play Services: The Verge reports that Android devices running version 7.0 and later can now log you into apps and websites without requiring you to type in a password. Using FIDO2, an open standard developed by the FIDO Alliance, the update instead uses your fingerprint or PIN to log you into various services.
