Yubico
Physical security keys for strong two-factor authentication
What Yubico does
Yubico provides hardware security keys that support multi-factor authentication (MFA) for securing digital accounts and systems. These keys typically work by requiring users to physically tap or insert the device as a second step when logging in, adding a strong layer of security beyond just passwords. The devices are often used to protect against phishing and account takeovers in both personal and business contexts.
Yubico’s keys are widely known for their usability with a range of online services and their focus on physical device-based security. They are relevant for organisations and individuals looking for hardware-based MFA rather than relying solely on software apps or SMS-based codes.
