If Hotel Tønderhus had your data

Look for Hotel Tønderhus’s own notice or letter: it should say what of yours was involved. Keep it.
Your email address is out: expect convincing phishing. Open Hotel Tønderhus by typing its address yourself, never through a link in an email or text, and check the sender before you reply.
Your phone number is out: ask your mobile operator for a PIN or port-out lock, so nobody can move your number to another SIM card and take your login codes.
Expect scams that use your details: calls, texts or emails pretending to be Hotel Tønderhus, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
