Servers are a able to request tokens using a new HTTP authentication method called “PrivateToken.” These tokens are then used as part of a cryptographic process to confirm to the server that the “client was able to pass an attestation check.”Īpple explains that these cryptographic situations are unlinkable, which means “servers that receive tokens can only check that they are valid, but they cannot discover client identities or recognize clients over time.” We’ll show you how your app and server can take advantage of this tool to add confidence to your online transactions and preserve privacy.Īs you should expect from Apple, this process is done with privacy in mind. Private Access Tokens are a powerful alternative that help you identify HTTP requests from legitimate devices and people without compromising their identity or personal information. The feature, which was spotted on Reddit over the weekend and by AppleInsider, was detailed by Apple in a WWDC 2022 session titled “Replace CAPTCHAs with Private Access Token.” In its explanation to developers, Apple explains: In turn, this allows you to completely bypass the CAPTCHA step. A new feature called Private Access Tokens will use a combination of details about your device and your Apple ID to inform a website that you are a legitimate user rather than a robot. With the release of iOS 16 this year, Apple is taking steps towards eliminating the need for those pesky CAPTCHAs around the web.
