ID is a service that allows you to create credentials for authentication to access online services. To create a ID, the user must indicate an email address and a password.

Your ID Credentials (username and password) are your identifying elements at ID and, as such, it is your responsibility to maintain their confidentiality. You shall be fully liable for all activities that occur under your password or account, and for any loss or damage arising from the use of said credentials under conditions that allow their decoding and copying.
MEO – Serviços de Comunicações e Multimédia, S.A. cannot and will not be liable for any loss or damage caused by misuse of your credentials not attributable directly or indirectly to MEO, by way of fraud or gross negligence or arising from your failure to comply with this Section.
If the service is used by third parties with recourse to Registered User login details, with or without User permissions, MEO – Serviços de Comunicações e Multimédia, S.A. consider that access and operations were made by the Registered User, and is not responsible for the abuse or fraudulent use of Access Data, unless proven otherwise.
