I lost a good friend/player a few years back. He played on a Mac and his game account (not ESO) got hacked. Said he tried to work with support to get it back, in the end he never got the help he wanted or needed and quit the game.
Funny how the loss of one player can affect how you play from then on. To me that game was never the same after he left. Eventually I gave up the game as well.
Since then I have tried to be aware of password changing.
I took a cybersecurity course recently and the teacher/expert said that making people change their passwords regularly (like businesses do) is a terrible idea. As the poster above me said, if you're using complex unique passwords for every service/site, changing the password isn't going to do anything. It can make people write them down in insecure places because they don't want to have to remember a new password every 6 months or whatever arbitrary time period is chosen.
