Login problems

Post by SeanNZ » Mon Aug 19, 2019 5:12 pm

I've been happily running Linux Mint on my laptop for well over a year but suddenly when I came to log in this week it asked for a login password. Only problem is I did not create a login password to start with. Instead opting to simply have a master for logging into browsers and updating the system.

I tried using that password but it does not work! I have no idea where this log in came from or why its even there. I wonder if someone hasn't hacked my system? I suspect I might need to do a complete re-install but this is going to mean a lot of effort goes down the drain and a few files I had not had the chance to back up too.

Has anyone else had this problem and if so is there a "work around".

As always any help gratefully appreciated.

There never was a login password to start with. It simply appeared. Only a master password. May be easier to reinstall I suspect.

Still thanks for the link. Appreciated.

Hello, SeanNZ.

On the operating system level, there is no such thing as a master password.
When you installed Linux Mint the installer will have asked you to create a first Linux Mint user account.
Let us assume that you named the account seannz.
This user seannz has been created by the installer as a user of type "administrative user". This means that this user is a member of the user group sudo. Members of the user group sudo are permitted to run commands and applications with root permissions.
In order to do so they have to authenticate by entering their own password.
As a consequence, when creating user account seannz the installer will have asked for a password. This is the password of user seannz.

If now for which ever reasons this password is no longer accepted or you simply do not remember this password any longer, the steps given by forum user pjotr will help recover from this problem without re-installing from scratch.

Regards,
Karl
