A certificate error occurs when a website’s security certificate is not recognized by your browser. This can happen for a variety of reasons, such as the certificate being expired, invalid, or issued by an untrusted certificate authority. Certificate errors can be a major security risk, as they can allow attackers to intercept your data or impersonate the website you are trying to visit.
There are several ways to avoid certificate errors. One is to make sure that your browser is up to date. Browsers are constantly updated to fix security vulnerabilities, so using the latest version will help to protect you from certificate errors. Another way to avoid certificate errors is to only visit websites that use HTTPS. HTTPS is a secure protocol that uses encryption to protect your data from being intercepted. You can tell if a website is using HTTPS by looking for the lock icon in your browser’s address bar.
