Information on FNMT natural person certificates (AC FNMT Users)
Since March 1, 2015, the FNMT is issuing a new type of natural person digital certificate. This certificate is issued by a new authority called "AC FNMT Users", instead of the already known " FNMT Class 2 CA", which provides a more powerful signing algorithm and key length.
These new certificates have a validity period of 4 years and allow a single renewal of the certificate by electronic means during the 2 months prior to its expiration. After the first renewal of an AC certificate FNMT Users, after the validity period of another 4 years has elapsed, the citizen will have to request a new certificate through the usual procedure, going to a registry office .
FNMT Class 2 CA certificates issued before March 1, 2015 remain valid until their expiration date and can be renewed through the FNMT website ##2##as long as it does not come from a previous renewal. With this renewal you will obtain a certificate from the new authority "AC FNMT Users".
If your FNMT Class 2 CA certificate does not come from a previous renewal, you can benefit from online accreditation with this certificate and obtain the new AC FNMT certificate ##2##Users without the need to go to a registry office.
