Paypal has just brought in the mandatory 2FA so you have to register your mobile number with them so they can send an SMS to verify your purchases. They don't offer you the option to use a landline and its a pain the the arse to be honest because I often purchase several times per day using Paypal and don't get a mobile signal in my office so have to keep going outside to get the SMS to input into Paypal.
I have set it to remember my device but that box doesn't seem to make any difference to the amount of times I am forced wait for an SMS to be received.
