Accounts and passwords

Messages, links and scams

When something goes wrong
- Change the password from a clean device, then contact your bank if money is involved.
- Report it: the FTC (US), Action Fraud (UK), the Canadian Anti-Fraud Centre, Scamwatch (Australia) or, in India, the cybercrime portal and 1930.
- Follow what to do if your email is hacked.
