Given the security breaches that occurred in 2017, changing your passwords is a great idea. But if you change them, you should keep a log of your new passwords. Why? Well, for one thing, taking into account how many passwords are required these days (even some food/recipe sites require them for some reason!) and the requirements some sites have (the Department of Defense’s password requirements are the worst I’ve encountered!), it’s just a good idea to have a log to help you remember them. But also, should you pass away or become incapacitated, your loved ones might need them.
So for security’s sake, change your passwords over the next week or so to new, more secure ones (not something like password). Create a password log while you’re doing so.
And if you need a password log, look no further.
