We count on emigrate builders utilizing GIS’s One Faucet and Auto Signal-In options to FedCM over the subsequent yr on account of the Chrome browser’s plans to deprecate third-party cookies. For many builders, this migration will happen seamlessly by backwards-compatible updates to the GIS JavaScript library; the GIS JavaScript library will name the FedCM APIs behind the scenes, with none developer modifications required. Nonetheless, some web sites could require minor modifications, akin to updates to customized layouts or positioning of sign-in prompts.
