We're pleased to announce that Recommendation X.1285, incorporating the OpenID Connect Core 1.0 - errata set 2 specification, has been officially published by the International Telecommunication Union.

Following the formal adoption in April 2025, which we announced in May, the specification is now publicly available.

This publication marks a significant milestone as the first OpenID Foundation specification to achieve ITU standard status, placing OpenID Connect Core alongside other internationally recognized identity specifications, such as OSIA (ITU-T X.1281) and FIDO2 (ITU-T X.1277.2 and ITU-T X.1278.2).

What this means

The publication of ITU-T X.1285 provides implementers with even greater confidence in the stability and international recognition of OpenID Connect Core. With the standard now used by billions of people across millions of applications, this ITU recognition enables:

• Enhanced global interoperability
• Stronger foundation for regulatory compliance
• Increased adoption in jurisdictions requiring internationally recognized standards
• Clear pathway for national policies and digital identity frameworks.

Thank you

This achievement represents years of collaborative work between the OpenID AB/Connect Working Group, and national delegations worldwide. We extend our gratitude to everyone who contributed to making this vision a reality.
