What to do if your email was in the Madison Square Garden Sports breach
1
Change your Madison Square Garden Sports password immediately
Log into Madison Square Garden Sports and change your password to something strong and unique — one you have never used anywhere else. A password manager after a breach can generate and store a unique password so you never reuse one.
2
Change any account sharing that password
If you reused this password elsewhere, walk the password-reuse change checklist. You can also check whether that password appears in known leaks without sending the password itself.
3
Enable two-factor authentication
Turn on 2FA or a passkey after a breach on Madison Square Garden Sports and every important account. Even if your password is known, attackers cannot sign in without the second factor.
4
Check your other accounts for this breach
Run a full email scan to see every breach your address appears in — not just this one. Then follow the after-breach playbook. If a password from this incident is still in use, check it without sending the password itself.

Shrink people-search listings if your name or address was exposed
A leaked email plus a public people-search page makes phishing more convincing. That is a separate job from changing passwords. See the data broker opt-out guide for official forms and, if you want help, removal services.
