Private Access Tokens (PAT)
When a visitor is presented with a Challenge Page, Cloudflare evaluates various signals - including the presence of a Private Access Token (PAT) - to decide which challenges to issue. If a visitor presents a valid token, certain challenges are not issued, which reduces the number of steps required to pass.
A PAT does not automatically solve a challenge or let a visitor bypass the Challenge Page. The visitor still encounters the Challenge Page regardless of whether they have a valid PAT.
While some challenges require interactivity, most challenges served are invisible to the visitor.
