Can I register PayPal using a protonmail account?

During this time I used a Google account to register PayPal.

Now there have been many websites and applications that offer ways to get paid via the internet / online and recommend withdrawal of funds using a PayPal account.

At the moment I still get a little information about the flexibility of this Protonmail account for online payment registration (Paypal, Payeer, Uphold, and others).

Please confirm about my question. Thank you
