Are google cloud messaging tokens unique?

Question

Could someone tell me whether Google cloud messaging tokens are unique?

Answer 1

Yes, Google cloud tokens are unique. Tokens are nothing but an ID, or registration token issued by Google cloud messaging servers to the client apps. Because only having that will help you in receiving messages. Google cloud messaging has been deprecated 2 years back in 2018, and it has been replaced with Firebase cloud messaging (FCM).
