An SSL Certificate is a digital certificate issued for a domain by a central authority called the Certificate Authority. To be issued an SSL Certificate, you must purchase an SSL Certificate and then go through a verification process conducted by the Certificate Authority.
An SSL Certificate does 2 things:
1. Encrypt the information sent from your user's browser to your website
2. Authenticate your website's identity.
By doing these 2 things, an SSL Certificate protects your customers and in turn increases their trust in your online business. This is especially important if your website requires users to login using passwords or enter sensitive information such as credit card details.
SSL Certificates are compatible with all major browsers.
Unfortunately, we don't support upgrades/downgrades at the moment. If required you can purchase a new certificate and install it on the same web server as the old certificate
While it isn't difficult to install an SSL Certificate, it does involve following a series of steps. You can find more information in our KnowledgeBase.
