Yubico AB is a cybersecurity firm that designs and manufactures hardware-based authentication devices to protect digital identities and secure access to IT systems. The company's core product is the YubiKey, a physical security key that supports multiple authentication protocols—including FIDO2, WebAuthn, and FIDO Universal 2nd Factor (U2F)—to deliver multi-factor authentication (MFA) and passwordless login capabilities. Yubico also offers the YubiHSM, a hardware security module for protecting cryptographic keys on servers. The company generates the vast majority of its revenue (approximately 84% as of Q3 2025) from the direct sale of its hardware products. The remaining 16% of revenue comes from its enterprise subscription services, such as YubiEnterprise Subscription and YubiEnterprise Delivery, which manage the deployment and lifecycle of YubiKeys for organizations. Operating globally with dual headquarters in Sweden and the United States, Yubico serves a broad spectrum of industries, including technology, financial services, healthcare, manufacturing, and government sectors. The company is a core contributor to open authentication standards and provides security hardware that mitigates the risks of credential theft and account takeovers.
