When attempting to access a website that is secured with an invalid certificate, this can lead to issues. In Google Chrome, you might encounter a "Privacy Error" page instead of the expected website. On this page, a warning that states "This is not a secure connection" is displayed. In more detail, you might see the error code NET::ERR_CERT_INVALID, indicating a problem with the website's security certificate.
Usually, for security reasons, it is advisable not to continue using a website with such an error. However, there are situations where you might be certain that the website in question is trustworthy despite its invalid certificate, and you wish to visit it nonetheless.
In these cases, there is a somewhat hidden method to persuade Chrome to load the website despite the invalid certificate. Simply click anywhere on the "Privacy Error" page and then type in "thisisunsafe". Although it may sound like a joke, this is an actual method that has been tested and confirmed, especially on the macOS operating system.
Please note that this should be an exception. It is generally not recommended to open pages with invalid security certificates, as this can pose a risk to your personal data. Therefore, be particularly careful and only use this method when you are truly certain about what you are doing.
