Cl@ve Pin and Permanent Cl@ve have been implemented as identification methods on FACe in order to facilitate the submission of invoices for those users who do not have digital certificate. These identification methods are based on username and password, which greatly increase users authentication possibilities for invoicing the Public Administration.
These new identification methods make possible for citizens to interact with Public Administrations anytime, anywhere. It is possible to obtain a single-use identification (Cl@ve PIN) or long-term (Permanent Cl@ve). Both identification methods are present on FACe to submit an invoice as well as search invoices already submitted.
