What is onlykey
OnlyKey is a hardware security key and password manager used to add strong authentication and protect credentials for logins, admin access, and developer workflows. It supports common MFA and authentication standards (for example, FIDO U2F/FIDO2 and one-time passwords) and can also store and type long, unique passwords without exposing them on the host device. Typical users include IT/security teams and technical end users who want phishing-resistant MFA and a portable credential vault. The product differentiates through its focus on an offline, hardware-based secret store with programmable profiles and broad compatibility with services that support standard authenticators.
Hardware-backed secret storage
OnlyKey keeps passwords and authentication secrets on the device rather than in a cloud vault. This reduces exposure to endpoint malware that targets browser-stored credentials or local password databases. It also supports using the device across multiple computers without syncing secrets through a third-party service.
Standards-based MFA support
OnlyKey supports widely adopted authentication methods such as FIDO U2F/FIDO2 and one-time passwords, which helps it integrate with many SaaS and enterprise applications that accept standard authenticators. This makes it usable in mixed environments without requiring a proprietary mobile app. Standards alignment also helps with long-term interoperability as identity platforms evolve.
Portable password manager workflows
The device can store multiple credentials and output them when unlocked, enabling strong, unique passwords without relying on clipboard copy/paste. This is useful for privileged accounts, break-glass access, and shared admin workstations where installing software is restricted. It can also support multiple profiles to separate personal, work, and administrative identities.
Not a full IAM platform
OnlyKey is primarily an authenticator and hardware password vault, not a complete identity management suite. It does not provide core IAM capabilities such as user lifecycle management, directory services, centralized policy orchestration, or CIAM features. Organizations typically still need an identity provider and administrative tooling for provisioning and access governance.
Hardware logistics and support
Deploying a hardware-based approach introduces procurement, inventory, shipping, and replacement processes. Lost or damaged devices can create access recovery overhead and require well-defined backup and break-glass procedures. This can be more operationally complex than app-based authenticators for large user populations.
User experience and training needs
End users must learn device unlock steps, button sequences, and service enrollment flows, which can increase onboarding time compared with push-based MFA. Compatibility can vary by browser, OS, and service configuration, requiring testing and documentation. Some use cases may require additional configuration to align with enterprise security policies.
