About the OpenID Foundation

The OpenID Foundation (OIDF) is a global open standards body committed to helping people assert their identity wherever they choose. Founded in 2007, we are a community of technical experts leading the creation of open identity standards that are secure, interoperable, and privacy preserving. The Foundation’s OpenID Connect standard is now used by billions of people across millions of applications. In the last five years, the Financial Grade API has become the standard of choice for Open Banking and Open Data implementations, allowing people to access and share data across entities. Today, the OpenID Foundation’s standards are the connective tissue to enable people to assert their identity and access their data at scale, the scale of the internet, enabling “networks of networks” to interoperate globally. Individuals, companies, governments and non-profits are encouraged to join or participate. Find out more at openid.net.
