Set up Free SSL Certificate by Let’s encrypt

Enter your domain name and click on the Create Free SSL Certificate. It will automatically check your website and will also add the www version for the domain.

Every domain have two version one is with www and another is without the www. So you should install the SSL certificate for both the www and non-www versions.

It will create the SSL Certificate also for the www version of the domain as I mentioned above. Now it is the time for verification. It has three types of verification. But choose the Manual verification, because it is safer. You do not need to provide any login details to this website or do not need to change any code.

Just click on the Manual Verification and click on the Manually Verify Domain below.

It will create two verification files for your domain, which you need to upload to the website host.

Download the verification files one by one and save these.
Now it is time to upload the files to the host folder. The files are created by this website automatically. If you opted for the SSL install by the Let’s Encrypt commands the same files would be created under the root folder of the host. For that, you have to go through some coding processes.
This website does the coding part for you.

Log in to the host where the website is hosted. Go to the root folder, which is public_html by default. If your website is hosted on another folder then you need to go to that folder.
For a normal WordPress website, the default root folder is the public_html.

Create a folder named .well-known (do not forget to write the dot(.) before). The dot before the folder name/filename hides it. If you are not able to see the folder after creating it then go to the Settings menu and check the ‘Show Hidden Files‘.

Open the .well-known folder and create another folder named acme-challenge under it.

Now upload the two files you downloaded from the SSL for the FREE website.

Now very the uploads by clicking on the verification link provided by the SSL for FREE websites.

Click on both of the links one by one. It will show some random characters in a new tab of the browser. Or it may download the files from your host, depends on the behavior of the browser.

If none of them happens after clicking on the verification links then you need to go through the upload process again after deleting the folder on your host root folder.

If everything is working fine till now, the go-to the next step.

Now you need to paste the keys on the SSL on your host. Click on the Download SSL Certificate and it will give you the keys for your domain.

Now go to your host and find the SSL option, normally you can find it under the security option. Click on it and it will open the SSL window. Here you have to paste the Certificates keys you generated on the SSL For Free website. Just Copy and paste the keys one by one.

I am using Hostinger as my hosting provider. You may see a little different window depending on your Hosting service.

Now Finally click on the save/install button. It will Install the key for your website.

Now you check the SSL has been installed under the SSL option. It will show you the Certificate Issuer is Let’s Encrypt. And you can check the Expiration date of the Free SSL Certificate.

One more thing you can/should do is Force HTTPS. It will serve the website everywhere with the HPPTS version. It is highly recommended.
You can do this by clicking on Force HTTPS if your hosting provider has the option. Otherwise, you can do this manually. Check the next steps to Force HTPPS manually.

If you do not find the Force HTTPS option on your host you can do this manually by the code.
Open your .htaccess file and under it write the code as on the picture and save it.
It will force you to load the HTTPS version everywhere. It is recommended task to Force the HTTPS.
