No more fumbling for your phone or typing in codes—simply touch the YubiKey to authenticate and gain instant access. Its hardware-based security means there are no batteries, no network connectivity required, and no downtime—just reliable, tamper-resistant protection every time you log in.

For businesses, the YubiKey 5 Nano offers enterprise-grade security, supporting advanced protocols like FIDO2, Smartcard/PIV, and OpenPGP. It integrates seamlessly with Google Workspace, Microsoft Entra ID, and leading identity access managers, helping Irish organisations defend against phishing and credential theft while ensuring compliance and data integrity.

Yubico recommends having a spare YubiKey for uninterrupted access, so you are never locked out of your accounts. The YubiKey 5 Nano is built to last, with a durable, water-resistant, and crush-resistant design, securely manufactured in the USA and Sweden.
