Sign in with Google and Facebook should have gotten replaced with Sign With Wallet by now.
I love the browser extension option in ZBD. As a group, lightning users are more based on the desktop/laptop than on just mobile.
One feature that is definitely missing is register fingerprint and sign in and pay with fingerprint, upto, say 1000 sats, without any device at all. Nowadays most phones have fingerprint recognition, I should be able to touch the fingerprint sensor on any phone or Point of Sale terminal and then it pays a set amount of sats example 100 sats. Or I can touch then use voice authentication to speak the amount of sats to pay, like 2000 or 30k or 589 or whatever.
