I can't answer that because I rarely use paypal myself. In fact they banned one of my two accounts (personal, business) for using gift cards which makes me uninterested in using the other one more than once a year.

That aside, I've seen many normal people use it for the reasons I described: They don't want to type in their card number and they think it's unsafe to type in their card number. It's (literally) all in their head so don't think too hard about it.

The practical alternative is Apple Pay, but you can't use it on Android.
