When you enabled 2FA you would have been given a list of recovery codes. You should first try to use one of those to access your account.
If you do not have backup codes then login with your username and password. When you reach the screen to input your 2FA code, click ‘Can’t access your 2FA device or backup codes’.
This will then walk you through the process to recover access to your account. You will need to verify your email and verify a device you have used previously to login. It will then take 3-5 days for Cloudflare to review your request.
The only way you’ll be able to regain access is by having access to the email address of the account.
These links may help, but they only work when logged out
Hi,
Sorry, you’re facing issues with 2-factor authentication on your account.
We got back to you on the ticket.
If you face further issues, please get back to us on it, so we don’t discuss PII on this topic.
