Yes. Choose Sign in with Google on the sign-in or sign-up page, pick your Google account, and you are in. A new account uses your Google email straight away, no confirmation email needed.
Already have an account with the same email? Signing in with Google takes you right into it, and connects Google for next time.
Want to connect Google to your account? Open Settings and click Connect Google account.
Disconnecting Google works once you can sign in another way: a password or Steam.
We only see your email address from Google, never your password, and we never post anything for you.
Tip: two-step verification protects Google sign-ins too.
