have tried to load new software and itasks me for authentication password it is a 5 digit pword unknown to me I have tried to change the passwd in grub but although following instructions it does not change passwd

Its the same password you log in with

When you log on you have a password. It should be that one.

If you have set to login without a password and have forgotten the password it can be reset by following the instructions here

What makes you think its a 5 digit password? I suppose its possible that a particular piece of software may have its own password. I can't think of one but if your normal login password does not work let us know what software is requesting the password and also open a terminal by pressing CTRL, ALT and T together and giving us the output from the following commands

lsb_release -a; uname -a; id

We will try to assist further
