Google removes WPS for Wi-Fi Protected Setup on Android P. This is a protocol that allows a Wi-Fi device to connect to a router using a PIN or a button. This, however, is not considered very safe.
The pin-based authentication can be exposed to a brute force attack and PIN must be enabled by default on routers with WPS support. With Android P, Google seems to be planning to remove the feature. Users started to notice the change to the WPS-related Google Troubleshooter, which has now been flagged as discontinued (no longer supported). This has led to speculation that Google may not resume operation once P is released publicly.

Since WPS is a security issue and many new routers completely eliminate the feature, Google removes the operating system level. The feature was introduced a decade ago. Google has not yet commented on speculation.
