How do I choose between a hardware token and a FIDO security key?

Hardware OTP tokens are ideal for organizations with legacy authentication infrastructure and no WebAuthn support. FIDO2 security keys are recommended for modern cloud-first environments, offering phishing-resistant passwordless login. Excelsecu offers both product lines, allowing organizations to choose or mix based on their IT environment and compliance requirements.
