What was exposed, and what does it mean for me?

  • Your passwordpasswords

    The password for this account was in the data, either as written or in a stored form that can often be reversed when the password is short or common. Anyone with the list can try it on your email, bank and shopping accounts.

  • Your email addressemail addresses

    Expect messages that look like they come from this service or another one you use, written to get you to click a link or sign in on a fake page.

  • Other detailsusernames

    On their own these carry less risk, but they make a scam message sound more personal.

03

What should I do now?

In this order, for what this breach exposed.

1. Change the password, and every reuse of it

  • Change your Quidd password if the account still exists. Then change the same password on every other account where you used it, starting with your email.
  • Use a different password for each account. A password manager makes that practical: it creates long passwords and remembers them for you.
  • Turn on a second sign-in step, such as a code from an app or a security key, for your email, bank and social accounts. Your email comes first, because every password reset goes to it.

2. Expect phishing

  • Be wary of messages that urge you to act fast, ask for personal details, or link to an address that is slightly off.
  • If a message might be genuine, do not use its links or phone numbers. Go to the site by typing its address yourself.
