Password overload.

[Ravenshire]

Another quick fix is to have an account with two online password managers, so that you can use one and import your passwords into the other.  It doubles your exposure, but insures against losing the data.  Another answer is an encrypted notepad like Turtl.   I believe that Keepass runs locally so that you can keep your passwords in a file on your computer (encrypted).  It's probably also a good idea to back up all your passwords to a USB stick from time to time.

This is exactly how keepass (and all of it's forks, as far as I'm aware) works. I use it on four separate devices and have to manually copy the database about to keep them in sync. A small hassle for a higher level of security.
