FAQ
M2M Authentication FAQs
Quick answers to common questions about machine-to-machine authentication.
M2M (machine-to-machine) authentication verifies the identity of applications, services, and devices communicating with each other, without a human user in the loop. It uses credentials like API keys, client certificates, or OAuth client credentials instead of a username and password.
User authentication verifies a person logging in through a browser or app. M2M authentication verifies a service, script, or device calling an API directly, so it relies on machine-friendly credentials and protocols instead of interactive login flows like passwords or MFA prompts.
SSOJet supports industry-standard machine-to-machine authentication, including the OAuth 2.0 client credentials flow, giving your services secure, token-based access to protected APIs and resources.
Yes. SSOJet's M2M authentication scales from backend microservices and API integrations to IoT device fleets, so you can apply the same security model across your entire connected infrastructure.
