Re: [libreoffice-users] the password of Libreoffice

To the originator of this thread, I feel your pain and commiserate with
you.  As to the solution... I don't know.  I think the best answer I have
seen is to have a different password for every different type of file or
web sight, i.e. all write files or all calc. files...even they can be
individualized at will.  Then keep a special file with a benign, password
protected, name that holds all the passwords.  The secure password for this
file is carried around with you (until you have used it so many times that
you know it by heart.)
Of course, I inevitably forget to include a new password in the password
file!
By the way, thanks to all who replied to my cry for help with the
Formula/text difficulty in Calc.
Regards, David
