Use your OpenID.
When authorizing, only the player ID is sent. No other data, including the e-mail and password, is transferred.
You'll be sent to a login page for your Wargaming.net account. If you weren't logged into Wargaming.net, you'll have to input your login credentials (e-mail and password) then press Log in. Once your credentials are confirmed, you'll be able to continue the registration process. Your OpenID will be connected to the account so that we can reimburse your Store purchases.
