At some point PayPal decided that the default way I probably want to log in on mobile is to scan a QR code andโ€ฆ I have some questions.

(Such as, how am I supposed to scan a QR code on the screen of my phone when the camera is on the back of my phone?)

@nicklockwood looks like you have enabled Passkey login which should mean using FaceID to enable the login. Do you have password autofill & PayPal enabled in FaceID settings?
@nicklockwood it should look like this
@stvnsmth that looks to me like you're using the PayPal app, not the website (in Safari).
@nicklockwood late getting back to this one but it is the web app, you must be seeing a strange bug in your end I reckon
