What to do if fraud detection in Emma flags your email or phone number?

To see which breach your details were part of, open Fraud detection from your profile and tap Check details.

If your email address was in a breach

• Change the password for your email account, and for the service that was breached.
• If you've used the same password anywhere else, change it there too.
• Use a different password for each account. A password manager can help you keep track of them.
• Turn on two-factor authentication where you can, especially for your email account.

If your phone number was in a breach

• Be cautious of unexpected calls and texts, especially ones asking for personal or banking details.
• Never share one-time passcodes or security codes with anyone, even if they say they're from your bank or Emma.
• If you're unsure whether a message is genuine, contact the company directly using details from its official website or app.
