It doesn't work. It worked for my initial set up. Which is odd. Where you open the MS Auth app, in my case on android, let the camera scan the set up QR code and then the Paypal Web page dialog asks for a confirmation code from your app. This step initially worked. However, every other subsequent attempt to connect, configure or use the Microsoft Authenticator app results in it not working. I try to use the log in dialog and it says the codes are not correct or valid. So I deleted the entry in the Microsoft Authenticator app and then removed the method from PayPal and tried to set it up again. It does not even let me progress pass the initial QR code scan screen it tells me every code generated is incorrect. I am not going to try another MFA tool. I use Microsoft Authenticator with 20 or so services. I have no issues with those other services. In my opinion PayPal's implementation of MFA code generation is busted and does not work with the Microsoft Authenticator app. My thought is that the mechanism PayPal has for creating the Authenticator application QR code is not compatible with the Microsoft Authenticator app. Whether its some weird unintended math library issue, or some other strange issue its VERY ANNOYING. Almost makes me want to just not use PayPal anymore... i've been a PayPal user over 20 years.
