When I'm finished using my computer, I just put it to sleep. That way, any keystroke wakes it up and all is well. On those occasions when I have to shut the system down, the system insists that I enter a password to restart/ enter. The problem is that it keeps telling me that my username or password is incorrect. I have reset the password many times but the computer is adamant. No password, no enter. I may have to go thru 20 attempts to get back in finally. How can I set things up so that no passwords are required? No one except me uses this machine. I have no need for passwords. This of course has nothing to do with passwords for online sites. They work fine.
