id.gov.pt

Does not work for me. I logged in and tried to add my Carta de Conducao. The only choice for authentication was Chave Movel Digital, so I entered my phone number, received the code, but upon entering it, the app displayed "An error has occurred. Try again later or contact support." I tried two times last week, then two times today and it always shows the same error message. Also, there is no suggestion in the app how to contact support. Update: 6 months later - the same problem persists. The same error message and no response from customer service.

Works as expected. Had some trouble adding the DUA document, but after a couple of errors it worked.

It doesn't work for those who live abroad since it requires a Portuguese mobile phone number for Authentication
