Why can't I use my Google or Facebook account to login / sign up?
BlockSurvey's vision is to provide decentralization in its software. By this you truly own the platform.
This is achieved using Blockstack blockchain which runs on top of Bitcoin's blockchain. The identity and data ownership is facilitated using them.
Unlike Google account which is owned by the central provider, with BlockSurvey the account you create is owned by you.
Not by BlockSurvey, not by Blockstack. Just you.
This is the very reason we don't allow users to sign up using Google or Facebook.
