After a big breach headline, I saw login attempts on an account where I had reused an old password. Changed it. What else belongs on a short checklist?
Old password reused — weird logins after a breach headline

Unique passwords, sign-out other sessions, review recovery options, enable stronger sign-in. Repeat for email first if that was reused too.
Watch for password-reset emails you did not request. Confirm inside the real app, not the email.
A password manager ended my reuse habit more than willpower did.
