Digital Mobile Key (CMD) for Foreigners

The Chave Móvel Digital (CMD), or Digital Mobile Key, is an authentication system that allows individuals to access public and private digital services securely in Portugal. This initiative simplifies bureaucratic processes and enhances digital inclusion for both Portuguese citizens and foreign residents.

Why is the Digital Mobile Key Important?

Because foreigners who, for example, wish to establish companies online can only do so if they have a Digital Mobile Key. The CMD is a crucial tool for anyone needing to sign official documents digitally, access government portals, or conduct business in Portugal.

With CMD, foreign nationals can perform various operations without physical paperwork, including company registration, tax declarations, and contract signings.

Who Can Apply for a Digital Mobile Key?

Any Portuguese citizen or foreign national can request a CMD. This system is designed to facilitate legal, administrative, and commercial activities for individuals residing in or interacting with Portugal.

How to Activate the CMD?

For Portuguese Citizens:

• Activation can be done using a Citizen Card (Cartão de Cidadão), Identity Card, or Passport.
• The CMD links a mobile phone number to the civil identification number, enabling secure authentication.
• Once activated, CMD allows access to numerous digital services, including tax, social security, and banking portals.

For Foreign Nationals:

• CMD activation is possible using a Passport or a Residence Card/Permit.
• The CMD links a mobile phone number to the passport number or residence permit number.
• To activate CMD using a residence card or permit, applicants must have a Tax Identification Number (NIF), which is required for many legal and financial transactions in Portugal.
• With CMD, foreign nationals can sign official documents digitally, access government services, and conduct business remotely.

For Those Living Abroad:

Foreign residents outside Portugal can activate the CMD using their Passport. This ensures that even non-residents can securely access Portuguese digital services, make official requests, and handle business affairs from anywhere in the world.
