digitronic SmartLogon is a two-factor authentication (2FA) software solution designed for SMEs, industry, public administrations, authorities, and healthcare facilities. It implements user login to PCs and specialist applications using two authentication factors: - Something the user knows: a short PIN - Something the user has: a physical security token SmartLogon supports a range of security token types, including smartcards, key fobs, USB tokens, smartphones, and — as of June 2022 — the YubiKey 5 NFC by Yubico. The solution is designed to operate without the need for certificates or a Public Key Infrastructure (PKI), reducing the complexity of deployment and the required IT infrastructure. The software is targeted at organizations seeking access protection for workstations and applications without the overhead of large-scale certificate management systems.
