You use the same password as you login with. If you are updating in a terminal you will not get any feedback as you type your password. You can reset your password if you have forgotten it (Or were silly enough to set a blank password at install time) using this guide:

Thanks

Alas, unable to do as suggested, cannot reboot , there is no such thing as recovery mode
Mine is a single boot system

Hold SHIFT at boot, you will get Grub. It doesn't matter that you single boot. Grub is still used to get the OS loaded.

Sorry no, Grub is not installed, and when I ask installation I first
have to give password, which is not accepted.

It is or Ubuntu wouldn't load. If you run:

sud update-grub

YOu will see the kernels being added to the config (admittedly this changes nothing). Also if you run:

dpkg -l | grep -i grub

You will see it IS installed. How would the OS load if there was no boot loader????? Think about it.

I am so sorry, but none of your suggestions work. I am an old lady of 86
trying to get my authentication back, but holding shift during booting
says that it will bring me Grub, but the result is just giving me my
normal desktop. Working in the terminal with dpkg command only results
in ¨authenticate¨ a standard question to everything I try . Please help.

You can use a chroot from liveCD. OmgUbuntu has a guide called "sticking it to grub" after the chroot command is used, the commands you run will affect the installed OS rather than the live CD desktop session as usual. You can then run:

passwd foo

as you expect (change 'foo' for your Ubuntu username, obviously)

No, I am sorry to say that none of your appreciated suggestions worked. But my son visited me and he fixed the problem.
