WordPress Users want, when transmitting their private and very personal data, such as account data or login data, above all security for the transmission of their data. And they too have data that should remain secret, such as payment information from their online shop, etc. In times of hacker attacks on private PCs (and even more so on those of companies), it should be important to you that users who visit your website, are interested in the products offered there and order something can also assume that their data will reach you safely. You can ensure this by encrypting the data transmitted between the users and the website, using SSL or TLS. You don't even have to use an expensive service for this. It can also be done for free, with Let's Encrypt. This free service is offered by webhoster.de AG. This tutorial will show you how to install and activate a no-kill SSL certificate from Let's Encrypt, so you can use it with WordPress. But not only from the security aspect, you should use Let's Encrypt to encrypt the personal data of their customers and their data. Rumor has it that according to the algorithms, websites with SSL encryption also rank better. If you integrate Let's Encrypt into WordPress, you can also do something for the ranking of your website.

Advantages / disadvantages
SSL encryption generally has the advantage for you that the users who visit your website trust this setting. Because a secure encryption is also a great success for your online shop. If you do not have an encryption for your online shop, no user will trust you. A disadvantage, especially with the free SSL encryption of Let's Encrypt, is that the certificate is only valid for 90 days. This means that the SSL encryption is only valid for this limited period. However, 30 days before expiration they will receive a message offering them an automatic renewal.
