• If you use your card to make a payment in an app, for example for games, groceries or clothing, you may need a personal password and a one-time password received by text message to authenticate payments. You will not always be able to authenticate using your MitID in an app. Instead, you may be asked to authenticate your payment using a personal password and a password received by text message. See how to do it in the boxes above.
• When you shop online, you may experience rejection of your payment if your MitID has been blocked.
• You may also be asked to authenticate your payment using your personal password and one-time password received by text message instead of MitID. Get help on MitID.dk if your MitID has been blocked.

• I have entered my personal password incorrectly too many times:
  In that case, your personal password has been blocked. Learn how to create a new one in the boxes above.
• I have registered my (Danish) mobile phone number and do not receive a password by text message:
  Please check that we send the text message to the right mobile phone number. You can see it on the screen when you are authenticating your payment.
  Learn how to change the mobile phone number in the boxes above.
• I have registered a foreign mobile phone number and do not receive a password by text message:
  Some mobile network operators do not allow auto-generated text messages. You can contact your network operator to check whether they allow auto-generated text messages or whether they block them. If you have access to a mobile phone with a subscription in Denmark, we recommend that you use that phone.
  Remember to link the Danish mobile phone number to the card you want to use for online payments. See how to do it in the boxes above.
• I enter the one-time password received by text message but am told that the information entered is not correct.
  There are several numbers in the text message you receive. For example, there is also a message ID. Please check and enter only the 6-digit one-time password.
  

The error message that appears on the merchant’s website will briefly state what is wrong. Here is some information about the most common errors:

• The card has been temporarily blocked. This may happen, for example, if you have entered incorrect credentials too many times or if you have cancelled your payments many times. The card is only temporarily blocked for online payments. You can still use your card in physical shops. Please try again later.
• You need a personal password. This may be the case if you have never created a personal password. It may also, however, be because your personal password has been blocked. Please follow the instructions in the boxes above.
• The payment cannot be executed for security reasons.
  Our security system has stopped the payment in order to protect you. You can try to make the payment again or call us for more help.
• Technical error. There may be a temporary technical error. It often helps to try again later.
