[1 Oct 2025] [Partners] Finalized Singpass FAPI 2.0 Specifications Now Live & Upcoming October Engagement Sessions

Dear Partners,

Following our earlier communication regarding the FAPI 2.0 draft specifications, we are pleased to announce that the finalised FAPI 2.0 specifications are now available. This release includes additional resources to guide you through the transition, ensuring a smooth and secure integration.

What’s new?

We have updated the documentation to include several key sections to support your migration efforts:

• Finalised Specifications: The complete and finalized FAPI 2.0 specifications are now ready for your review and integration planning.
• Technical Concepts: A new section has been added to provide a deeper understanding of the core technical changes, such as Pushed Authorization Requests (PAR) and Demonstration of Proof-of-Possession (DPoP).
• Migration Guides: Detailed migration guides are now available to walk you through the necessary steps for updating your existing integrations to comply with FAPI 2.0.

You can access all of these resources at: https://go.gov.sg/spfapi2

Why is this change to FAPI 2.0 important?

This change will bring several key benefits:

• Bolstered Security: FAPI 2.0 provides a robust framework that protects against common security threats like phishing and token theft, giving your users greater confidence in your services.
• Streamlined Integration: By standardising on a single, modern protocol, this update will simplify future integrations and reduce long-term maintenance efforts for partners.
• Consistency and Scalability: This change creates a more cohesive system across Singpass and Corppass, preparing us for future enhancements and ensuring a consistent experience for all users and partners. Ultimately, this means you can spend less time on security and more time building innovative features for your users.
• Enhanced User Experience: This enhancement can make context-aware and progressive logins possible, allowing for a smoother user journey.

What else do you need to know?

• As previously communicated,
  • The deadline to complete your migration from Myinfo v3/v4 to Myinfo v5 is 30 September 2026.
  • All Singpass APIs must comply with FAPI 2.0 by 31 December 2026.
• Testing environment: We will be providing a dedicated testing environment at a later date to allow you to validate your FAPI 2.0 integration.
• Upcoming engagement sessions: We will be holding engagement sessions in October for a detailed walkthrough of the changes and addressing any questions you may have. More details are provided below.
