If we add these characters in your user name or password, others it seems the same display these characters, but in fact corresponds to a different user name and password, this approach greatly improves the security of the account. This proves that these characters will still be in separate storage and identification systems inside the machine.īy testing 256 ASCII coding, we found, There may be part of the character input but can not display and can be used as a user name or password。 Enter the corresponding user name after cancellation, a successful login.Įnter your user name in the wrong order or using blank line instead of 160 characters in the ASCII code, will result in login failure. A total of six characters as the user name, the ASCII code of 160 and blank lines similar. We tested a collection of these characters. We expand on the character test, all printable characters sequentially input to modify the user interface name, find the table of characters is not visible and occupy the actual position. Screenshot of the table is too long - not interested friends can look at their own search Obviously in addition to space, the other characters can be displayed for this test is not very meaningful. We first tested for control characters, obviously they will not - 2) printable characters In order to facilitate this experiment, the whole virtual test machine, the virtual machine version winxp, does not affect use on other versions 1) control characters Let's test in the end what characters can be used as a user name can not be displayed on the screen it? It is not a little look. Win + R to bring up the menu input operation "netplwiz", or enter a "user account" in search boxĬheck the "To use this computer, the user must enter a user name and password" option. The Interactive logon: Do not display last login was changed to enable Win + R to bring up the Run menu, enter "gpedit.msc", open the local policy group editor, select -Windows Settings - Security Settings - Local Policies - Security Options.
