FusionAuth 1.70 lets companies open apps securely to customers' AI agents

FusionAuth, a customer identity and access management (CIAM) platform, has released version 1.70. It adds Client ID Metadata Document (CIMD) support and OAuth token exchange, so companies can securely open their apps to customers' AI agents. The update targets firms building Model Context Protocol (MCP) servers, which must decide which AI apps may connect and what access they get. In FusionAuth's 2026 State of AI and Identity report, 88% of organisations said AI deployment is outpacing their identity and security infrastructure. Siteimprove, a design partner, uses it to register and authorise AI tools before they reach a customer's account. Both features are available now on the Enterprise plan, in FusionAuth Cloud, a company's own cloud, or its own data centre. FusionAuth does not charge per token exchange.

FusionAuth appoints Jamey Miller as senior vice president of engineering and technology.

FusionAuth appoints Jamey Miller as senior vice president of engineering and technology. July 21, 2026 Jamey Miller FusionAuth has appointed Jamey Miller as senior vice president of engineering and technology, adding an experienced software and product development executive as the customer identity and access management (CIAM) provider scales its engineering organization to support enterprise growth and increasing demand for identity infrastructure. In the newly created leadership role, Miller will oversee engineering and technology strategy, with responsibility for expanding the company's research and development organization, maintaining platform reliability, strengthening product quality, and preparing FusionAuth's engineering operations to support artificial intelligence-driven identity workloads. The appointment comes as enterprises invest in modern identity platforms to secure users, applications, AI agents, and connected services while balancing cloud, hybrid, and on-premises deployment requirements. "Identity has become mission-critical infrastructure, and AI is raising the stakes even higher - every new agent, every new surface, every new enterprise customer is a harder identity problem than the one before," said Brian Bell, chief executive officer of FusionAuth. "We're scaling to meet that demand, and that starts with the engineering organization. Jamey has done this before: built and scaled R&D through high-growth, high-complexity environments. That's exactly what we need right now." Miller brings more than 25 years of experience leading global software research and development organizations spanning engineering, product management, cybersecurity, information technology, and customer support. His background includes building engineering teams in high-growth software companies, managing operational transformation initiatives, and integrating acquisitions in private equity-backed environments. Most recently, Miller served as chief product and technology officer at enterprise software company Confience, where he led product and technology operations, improved software delivery processes, strengthened platform security, and managed the integration of Brazilian software company LabSoft following its acquisition. Earlier in his career, Miller served as executive vice president of research and development and operations at Convercent, helping guide the governance, risk, and compliance software company through its acquisition by OneTrust. Following the transaction, he became vice president of R&D operations at OneTrust, where he supported the expansion and operational management of a 400-person research and development organization. "Identity is becoming more challenging as AI applications, autonomous agents, and the rising security expectations of enterprise customers continue to reshape what authentication and authorization need to accomplish," Miller said. "FusionAuth is perfectly built for this environment and I look forward to successfully leading the company's engineering team into its next chapter." FusionAuth develops customer identity and access management software that enables organizations to manage authentication, authorization, and user identity across consumer-facing applications. Its platform supports passwordless authentication, multifactor authentication, single sign-on, OAuth, and other identity standards, while offering deployment options that include cloud, on-premises, and hybrid environments. The company said Miller's appointment supports its continued expansion as organizations increasingly prioritize identity infrastructure capable of supporting enterprise security, regulatory compliance, and the growing authentication demands created by AI-enabled applications and digital services.
