You’ll notice most sites have a lock icon next to the URL when you visit them. This is called a SSL (Secure Sockets Layer). What this does is encrypt your information entered into the website.
You can think of this like sending a written note through those pneumatic tubes you see at the bank and as your note travels through that, the information is scrambled and decoded once it arrives. This is to protect your information from people trying to intercept that.
This typically means you are trying to visit a potentially harmful website that you should avoid, or your date and time could also be off.
Check the date and time according to their region and if its incorrect then you’ll want to update it. You can search HelpCloud Search to find how to update your date and time for your operating system.
