Court grants Amazon preliminary injunction blocking Perplexity's Comet browser from Amazon accounts
Federal judge bars Perplexity's Comet AI browser from accessing password-protected Amazon accounts on behalf of users, citing unauthorised access concerns.
The injunction is the first US federal-court action specifically targeting an AI agent's access to password-protected accounts, populating the otherwise thin Regulation lane alongside the UK FCA's 2026 priorities (2026-w13-regulation-uk-fca-agentic-payments-priorities). The order draws a legal line between first-party agent deployment — Amazon Rufus serving Amazon customers (2025-w47-pilots-amazon-rufus-auto-buy) — and third-party agent access to the same accounts. Perplexity's parallel work on its free shopping agent (2025-w47-aeo-perplexity-paypal-instant-buy) sits outside the injunction's scope. The ruling foregrounds the authentication-versus-impersonation problem that FIDO Alliance later targets with its Agentic Auth working group (2026-w18-standards-fido-agentic-working-groups) and that Visa's Trusted Agent Protocol (2025-w42-payments-visa-trusted-agent-protocol) addresses at the network level.
