That is an awesome idea.
Using Google services in the wallet for authentication is a good idea???
Sorry, but I do not agree...
The idea of using crypto is to not rely on any central authority.
And from all central authorities, google is arguably the one with most centralized power already...
It was just an idea, not a suggestion that the team of experts KARMA will consider and decide. But .... tell me why you do not approve this method of protection since this is the most reliable at the moment and all exchanges trading coins explicit cue to be used for consumer protection?
I will give an example of what made me think of this protection: Imagine you keyloggers or trojan virus on your PC! ....
