I use password “groups”. And I vary the complexity of each “group” based on the sensitivity of the information the password protects.
I also store all of my work passwords in a password protected word document. It’s safe, though. The name of the document is “don’t open this”.
;-)
Just rename the file something innocuous...like "maindb" and then stick a .dll extension on it. It will still open in Word as a doc file but is easily overlooked by anyone snooping.
Personally, I use a small, free program called PINS. It resides on a flash drive and can also sit on your hard drive. One password opens the vault where you store URLS with usernames/passwords...etc. When you make password changes, just update the PINS database file. It hasn't let me down in 8 years.
I just use XXX file. :-)
