Apple has added an Android-like lockscreen feature to the employee-only Apple Connect application. Instead of entering a 4-digit code, users connect the dots to create an (arguably) more secure gesture-based passcode. It’s unknown if Apple will bring the new lockscreen to the public, since it’s very much in Google’s territory.
Apple’s implementation seems to be slightly different than Google’s: instead of just recording one string of up to 9 dots, users can record multiple strokes, increasing the security considerably; it would be much more difficult for a shady passerby to memorize a complicated chain of dots than a short 4-digit code.
The dot lockscreen is a defining feature of Android, so including it in iOS it would be blatant copying, but nevertheless, the added security would be welcome.
