Google Gives AP2 Payments Protocol to FIDO Alliance, Adds Preapproval

Google donated its Agent Payments Protocol (AP2) to the FIDO Alliance on April 28, 2026, and released a new version that lets agents make payments under instructions users approved in advance. Google announced AP2 in September 2025 as an open protocol developed with more than 60 organizations. It supports cards, stablecoins and real-time bank transfers. Signed digital “Mandates” record evidence of a user’s instructions. Version 0.2 adds “Human Not Present” payments, allowing an agent to act within permissions set before the transaction without the buyer present.
