During code-based registration, request the email code on the registration page after completing the displayed checks. Enter the latest code into the verification fields and complete registration. Use resend only when the page allows it.
If your account requires a separate verification email, open Email verification while signed in. Request a new message if needed, then follow its instructions. Verification does not log you into a different account.
Check the address you entered and your spam folder. If messages do not arrive, contact G2U Support. Keep verification codes and links private.
