You can create a Cloudflare account using your Nimbus Hosting email address, simply go to your account then integrations here

You should see the below panel, simply click the "Create Account" button

If you do not already have a Cloudflare account, the interface will update the button to say "Unlink Account" which allows you to remove the account from Cloudflare if you want to.

If you do already have a Cloudflare account with your Nimbus Hosting email, you will be given the option to enter your existing Cloudflare account password, allowing our platform to link to your Cloudflare account.
