Google, Facebook and many other services offer a single-signon system called OAuth2, which allows Vyew to verify your email address and log you into Vyew so you don't need to create a new login/password to remember. It is safe and secure.
Can Vyew access my email or post to my Facebook account?
No. Vyew is not given such access. You are only granting Vyew permission to access your name and email address.
