Mobiilivarmenne is a PKI-based authentication method run by Finnish mobile operators DNA, Elisa and Telia. Mobiilivarmenne is based on certificates that are located on the users’ SIM cards.

To use Mobiilivarmenne, you need a SIM card and an activated subscription from one of the operators. Given these requirements, you can use a mobile device such as a smartphone or feature phone as an authentication method for different services. Currently, only the authentication PIN code is used, although the operators have development projects for activating signature PIN codes. In all Signicat services, the authentication PIN codes are used.

In the production environment, all Mobiilivarmenne accounts roam between the operators. This means that a service provider can establish one agreement with one of the operators to provide the service for all end users.
