Cloudflare - Get Account ID

You will occasionally need to find your "account ID" when performing actions such as filling in the details to perform Cloudflare DNS-based challenges for Let's Encrypt. I kept forgetting how to do this so I made this super small tutorial.

Steps

Go to https://dash.cloudflare.com/.

Click on the three dots beside the account you care about. E.g. which one manages the DNS records you care about. Then click on Copy account ID right at the very bottom of the looooong list.

That's all folks!
