If you have a domain or hosting account on Namecheap and wanted to enable or disable auto renew option then follow these steps to avoid automatic renewal. I personally use Namecheap account for buying domain and used it for hosting account as well. However, I found that Domain service is pretty much good as reliable to Hosting. When you buy a domain or hosting account with Namecheap then by default the auto-renewal is turned-on. And in case if you don’t want to renew it, but forgot to disable auto-renew option then the system itself will renew it and charge to your credit card.
So, lets find how we can enable or disable auto-renewal option on Namecheap account by following below steps:
1) Type Namecheap.com on Chrome browser and hit Enter.
2) Click on SIGN IN link located on top corner left hand side.
3) Enter your Username and Password and click on Sign In button as show below:
4) Scrawl down a bit and and it will show all available Domains and Hosting plans.
5) Click on Arrow button 
beside the domain for which you want to disable auto-renewal option.
6) A menu option will open, click on Radio button “Auto Renew” in order to enable or disable domain or hosting renewal.
Using this option, you can also enable or disable auto-renew for SSL certificate as well.
