Re: [libreoffice-users] the password of Libreoffice

Yes, that works, unless you system does a crash/burn and for some reason
you cannot get all of your "files and data" off your backups.  Oooops,
sorry you forgot to backup that file somehow.

I am rebuilding a desktop back after the primary drive failed and I did
not have 1 to 2 weeks of work on the backups, and "certain" config files
were missed in the backup "process".  The drive died the day I was
scheduled to backup the work for that week or so.  Now I have a new
drive, double the size, but still working on getting all of those bits
and pieces of packages and utility configuration back to where it should be.

So a password manager can work fine, if you are on the system where it
is stored and you somehow do not loose it in a crash and burn of a disc
drive.  Writing it down on paper and securing it somewhere safe will not
depend on proper backups and sharing the password management "system"
between several computers you might use - i.e. desktop and laptop, and
maybe a tablet.  Paper is also not software dependent if you run
Windows, Linux, and Android systems.  I do.
