"Web Bot Auth is an experimental cryptographic protocol used to authenticate requests sent by bots. Instead of relying solely on self-reported headers and IP addresses, Web Bot Auth allows agents to cryptographically sign their requests."
"Using Web Bot Auth helps website owners identify automated traffic on their sites, and prevents other actors from attempting to spoof reputable agents."
"Web Bot Auth can bring the following benefits: Cryptographic certainty, better observability, and future-proofing for establishing mutual trust between agent providers and websites."
Web Bot Auth is a new cryptographic protocol developed by Google to authenticate bot requests. It aims to improve security by allowing bots to cryptographically sign their requests, moving beyond self-reported headers and IP addresses. This protocol helps website owners identify automated traffic and prevents spoofing of reputable agents. Benefits include cryptographic certainty, better observability of agent interactions, and future-proofing for mutual trust between agent providers and websites. Currently, not all Google user agents utilize this protocol as it remains experimental.
