What steps should I take after a data breach with reused passwords?

I just got a notification that my password was in a data breach from a site I haven't used in years. I changed it there, but I’m worried because I know I reused that same password on a couple of other, more important accounts a long time ago. I'm not sure if I should just change those now or if there's something more I need to do since that old credential is already out there.

That alert hits hard. I had something similar a while back. I changed the breached site and then started rotating all my major logins. I ended up using a password manager and generating random, unique credentials for each account. I also turned on two factor authentication wherever possible. It felt like a lot at first, but I slept better after a day or two.

I moved fast on enabling 2FA for the big ones, then I went through a list of sites I’ve used with that same credential and swapped them one by one. It took a weekend, but I could tell the heat died down after a while.

Maybe the bigger issue isn't that single leak, but whether those accounts still matter as much as we think. I keep circling back to the idea that I may be overreacting about sites I barely used years ago.

I tried to do a sweep but hit snags with some sites' reset flows and I worried about getting locked out. So I paused, then started again later with a calmer plan. Not done yet.
