Ability to add email, social logins to wallet accounts

It would be good to add the ability for wallet users to add their email to their accounts.

Right now, if a user logs into Venice with their wallet then there’s no way to add an email or additional social accounts that can be used to log in. 

Ideally, I want to be able to log in with my email or google sign on to the same wallet that my wallet is connected to (even if I can’t take all the actions where there’s a signature needed).
