What to do right now
- Change your password for this service now. And change it anywhere you reused the same password — attackers try leaked passwords on other sites within hours ("credential stuffing").
- Turn on two-factor authentication. Even a leaked password is useless against an account protected by a second factor. Prefer an authenticator app over SMS.
- Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
- Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
- Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
