The new tokens dubbed Private Access Tokens (PATs) will eliminate the need for CAPTCHA across the web.
They can also validate users without maintaining a cumbersome SDK.
For Cloudflare customers, it will automatically ask for and utilize PATs.
PATs vastly improve privacy by validating without fingerprinting, which is the most powerful aspect of the new technology.
Cloudflare will be incorporating PATs into other security products very soon.
