What to do right now

1. 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").
2. 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.
3. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
4. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
5. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
6. 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.
