Allow signing into Blynk account by Gmail or Apple or Amazon in addition to FB

The use FaceBook to sign up for a Blynk account from the app is useful. I would love to have sign up by Google or Apple or Amazon account. It may be easy to onboard users that way. Although, I have no idea what kind of information is lost when Google or Apple or Amazon fronts the user account.



It is necessary to negotiate with them, to confirm the reliability of the application’s security. This seems to be why mail is used.
