How do you block your MitID if you think it has been misused?

Three ways to stop misuse

Answered at: Checked at:

Short answer

You can block your MitID temporarily yourself through the self-service on mitid.dk. If you cannot do it yourself, call MitID Support on 33 98 00 10, which as of November 2026 is open 8.00–20.00 on weekdays and 10.00–16.00 at weekends. Outside these hours you can have your MitID blocked by calling Cyberhotline on 33 37 00 37. If a MitID device such as your phone or code display is lost or in the wrong hands, block that device at once.

Practical info

Why

  1. A temporary block helps when you suspect misuse but still have your device.
  2. Support has long opening hours, also at weekends.
  3. Cyberhotline covers the hours when support is closed.

Details

If others have had access to your MitID, also contact your bank to stop any transfers and report the misuse to the police.

Tip

Save 33 98 00 10 and 33 37 00 37 in your phone now, so you do not have to search for them in a hurry.

What may differ

Opening hours of MitID Support can change, so check mitid.dk before you ring.

Common misconception

You can only block MitID when your bank is open.

What actually happens

You can block MitID yourself online, by phone with MitID Support or outside opening hours through Cyberhotline.
