If Instant Checkmate had your data

  1. Look for Instant Checkmate’s own notice or letter: it should say what of yours was involved. Keep it.
  2. Change your Instant Checkmate password, and the same password anywhere else you use it. Turn on two-step sign-in.
  3. Expect scams that use your details: calls, texts or emails pretending to be Instant Checkmate, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
