SSL Certificate
A digital certificate encrypts the connection between your browser and a server. You can recognize it in your browser by the padlock icon next to the address. It ensures that form data, logins, and payment information cannot be intercepted. An SSL certificate builds trust with visitors and is now standard practice, not just for online shops.
A certificate encrypts the connection between the browser and the server. Without one, every browser marks the page as insecure, and forms become a risk. It has been mandatory for years, not optional, and thanks to Let's Encrypt, it usually costs nothing.
Two things are often overlooked. First, renewal: Let's Encrypt issues encryption for 90 days, and renewal must be automatic; otherwise, the site will eventually display a warning. Second, mixed content: If an encrypted page loads an image via an unencrypted address, the browser will block it. This is the most common error after a website migration.
