It’s pretty helpful for online shopping to be able to use Apple Pay. On your phone, you just click the button, use FaceID, and confirm shipping address. It can be done in 2 seconds compared to regular checkouts which step you through 4 or 5 screens.

Sign in with GitHub has also been nice for me on gitter. I don’t need a separate gitter account for any reason, and sharing my GitHub account on gitter is reasonable.
