Here’s a good reason to update to your latest version of Google Play Services: 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.
While complex passwords can be a secure method to keep your account safe, they are often long, hard to remember, and should be updated periodically (unless you use a password manager.) Two-factor authentication is helpful too, but can be annoying and difficult to access if you’re traveling internationally.
