Use a recovery code you saved when setting up two-factor authentication if that option is offered. A recovery code works once. If you still have an authorized signed-in device, review the available account-security controls there before signing it out.
Do not send support your authenticator secret, QR code, or remaining recovery codes. If no valid recovery method remains, describe the access problem to support using your account email. Support must review account access; an email message, team name, or support code is not permission to bypass a second factor. Do not remove another person's security methods to regain access.
