Cancel the Digital Mobile Key

The Digital Mobile Key (CMD) can be cancelled at any time.

There are some situations when you need to cancel the Digital Mobile Key in order to activate a new one, such as when:

you activate a CMD using the access data to the Portal das Finanças, and do not receive the letter by mail
you have your mobile phone number associated to a family member's CMD registration and now want to activate a CMD for yourself with that mobile phone number
you want to change data such as adding Social Security, SNS or NIF number to the CMD registration
change the type of identification document

For example, if you have activated the CMD with a Residence Card and, in the meantime, you have obtained Portuguese nationality and the respective Portuguese Citizen Card, you must cancel your current CMD in order to activate the new one with the Citizen Card.
