You can sign in with a WhatsApp one-time code or continue with a Buckhy account. Phone numbers are unique; impersonation is not allowed.
Keep the device and number you used to sign in. You are responsible for activity under that account.
If an account is suspended, sign-in is blocked until the team reviews it. Use the Contact page with the phone number on the account.
Admins can link a Buckhy identity from Account → Settings. Attendees do not see that panel.
