It's been, like, a year since I started using KeePass and I still haven't changed the p/w to all my accounts yet! The important ones are done, the ones remaining are a bit bleh, but I still need to change them all.
I don't use a p/w manager at work, I just use a text file with all my usernames and passwords in it. This is in protest at IT insisting on using separate usernames and passwords instead of my Windows login to determine access in certain programs and systems. Oh, also, one system has the most ridiculous constraints of pw's EVER. 8-10 characters, no two consecutive chars the same, no pw that's "too similar" to the previous pw (no idea how that is defined!) so you can't just add 1 to the number... Unbelievable.
