Frequently Asked Questions

What is an SSL certificate?

An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection between a user's browser and the web server.

What is the difference between TLS and SSL?

TLS (Transport Layer Security) is a newer, more secure version of the SSL protocol. Modern "SSL certificates" actually use the TLS protocol. TLS 1.2 and TLS 1.3 are the recommended versions.

How often should I renew my SSL certificate?

SSL certificates are typically valid for 90 days to 1 year. It's recommended to set up automatic renewal or renew your certificate 30 days before expiration.
