Twitter (200M) data breach

Security remediation checklist

Work through these steps, most urgent first:

1. Turn on two-factor authentication (authenticator app or security key) wherever it is offered.
2. Watch for identity fraud: unexpected letters, credit applications or accounts in your name.
3. Expect targeted phishing emails that mention this breach. Do not click unexpected links.
4. Check other accounts that use the same username or email and secure them.
5. Review the privacy settings of your online accounts and limit what is publicly visible.
6. Keep an eye on your accounts for logins or changes you do not recognise.
7. Subscribe to breach alerts so you hear about future breaches quickly.
