If you had to choose two universal annoyances when browsing the web, without a doubt, the list would be headed by the omnipresent notices to accept cookies and those known as CAPTCHAs, those tests that allow the server to know if you are a human or a robot.
Do You Know What We Have Posted on

Good news: everything points to the fact that soon we will finally be able to say goodbye to seconds. Apple, Google, Cloudflare and Fastly have been working for years on a protocol, Privacy Pass, which will allow an Internet user to be identified as a legitimate person and not an automated account. Apple, in fact, will include support for this feature in iOS 16, iPadOS 16 and macOS Ventura, the operating systems that will arrive on the company's devices in the fall.

CAPTCHAs were born in the year 2000 as a way to prevent automated accounts from abusing certain web services or creating false users in different ones. These are small tests that are in theory easy for a human but very complex for a computer, such as reading a text that is distorted or hidden under a color pattern.
The name is an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart, and newer versions take advantage of the test to help train machine learning algorithms. It is the reason why some CAPTCHAs ask you to identify motorcycles, pedestrian crossings, cars or traffic lights in photos taken at street level.
This type of testing may seem like a minor inconvenience, but it has several drawbacks, especially for users with disabilities. The simplest ones are also not very effective when it comes to separating humans and bots, because today some of the tests that were initially considered complex for a machine are trivial.
Furthermore, they are a considerable waste of time. According to Cloudflare, every day humans spend an aggregate time equivalent to 500 years in solving CAPTCHAs.
Privacy Pass replaces these challenges or tests with an access identifier that confirms that the user is human and that is generated automatically when using the phone or computer in the normal way. Actions such as biometric identification or the way the phone is held and moved allow the system to attest that access is being done legitimately.
The identifier is completely anonymous and random, which adds another advantage to the identification process compared to conventional CAPTCHAs, which record the user's IP number. Hundreds of services will support this tool in the fall, with many more to follow in the coming months.
