Authentication protocols serve as the backbone of online security, enabling users to confirm their identities securely and access protected information and services.
The protocols exchange information to verify the validity of the authentication service and confirm that the claimant possesses the appropriate token to authenticate their identity.
With myriad authentication protocols available selecting the appropriate one for your organization can be daunting.
Following are the key authentication protocols, along with insights into choosing the right one for your business needs.
The Authentication Protocol Landscape Each authentication protocol offers unique features tailored to specific use cases and security requirements.
If you're trying to figure out which one is best for your business, consider these four authentication protocols and their potential use cases.
OpenID Connect is an open standard that builds on OAuth by providing authentication capabilities using an ID token to verify user identity securely.
OIDC suits scenarios in which interoperability and user authentication across multiple systems are crucial, such as in federated identity management systems.
SAML offloads authentication responsibilities to specialized IdPs, reducing the burden on SPs and enhancing security.
SAML works best for single sign-on authentication in enterprise environments, where centralized authentication and access control are essential.
SAML's reliance on XML may also introduce complexity owing to it being an older format than more modern ones, like JSON. FIDO2/WebAuthn: FIDO2 is an open standard for passwordless authentication that relies on registered devices or hardware security keys to verify user identities.
WebAuthn, a component of FIDO2, enables passwordless authentication through possession-based and biometric methods.
You may want to consider WebAuthn for consumer-facing applications and mobile-first experiences, leveraging native device capabilities for seamless and secure authentication.
You should consider TOTP for various authentication scenarios that require enhanced security.
Factors in Selecting an Authentication Protocol It's easy to generalize which of the above four protocols you should use.
Business applications targeting enterprises should use SAML because of its robust SSO capabilities and centralized authentication management.
Consumer and mobile applications should pick WebAuthn/passkeys to provide a seamless and secure authentication experience that leverages native device features, like biometrics.
Authentication method: Consider the authentication methods your users prefer and select protocols that align with their expectations and UX preferences.
Choosing the right authentication protocol is critical for maintaining the security and trust of your users.
By understanding the features and use cases of different protocols and considering factors such as security, integration, scalability, and user experience, you can select the most suitable protocol for your organization's needs.
