In earlier versions of Windows, there is a possibility of brute force password cracking, no matter how complicated the password is. The Win8 system uses a very special image Password Logon function to prevent viruses and Trojans. This logon method does not contain the regular characters of deep technology, viruses and Trojans cannot be cracked, which obviously greatly improves the system security defense capability.
When you use the image password to log on to Windows 8, you can first move the pointer to the right of the screen, the charms control panel is displayed, select the "set" option, click the "change computer settings" button at the bottom to go to the computer settings change page. From the list on the left side of the page, click the "user" tab to expand the tag settings page.
Next, click "Create Image password" at the "Logon Options" location on the page to bring up the image password creation wizard dialog box. Follow the prompts to enter the old login password first, select another image that you are very familiar with. We suggest you use images that are relatively regular or have special content, because the password you enter in the future can only be a straight line, circle, and point. If you select a straight line or circle, the length and size are different. This is easy to forget, so the best way is to click, in addition, it is best to select a special location in the image. In this way, you can use the image and password method to log on to Windows again in the future. Even if you tell others, you don't have to worry about brute force password cracking.
