Ubuntu – Authenticate user that has no password?


I've set up my user account so that no password is required to login and I need to install some updates. However when prompted for the password, it says authentication failed if I leave the box blank. I don't have a password, how am I supposed to authenticate?


I tried the method in Reset lost administrative(root) password but it came out with an error: Authentication token manipulation error password unchanged. What does this mean?

  • Auto login is not password less, it just bypasses the password and logs you in automatic. you still have a password, its the same one you used for the installation and the installation wont run if the password box is empty. You must have used something to install, that is the same password you need atm.
