Authentication for autonomous agents
Prism Auth is the API that lets browser agents securely store credentials, persist sessions, and handle MFA — without leaking secrets into prompts or code.
How It Works
Three simple steps to secure, persistent agent authentication.
Store Credentials
Store or create credentials for websites that you haven't logged into before with full encryption.
Check Sessions
Check for existing sessions before taking action. Skip login when already authenticated.
Authenticate & Run
Handle login automatically when needed, including MFA. Run seamlessly behind any login wall.
Core Features

The Agent Authentication Problem
Current solutions are brittle, insecure, and break with modern authentication requirements.
Brittle Hacks
Agents can't log into apps without fragile workarounds
Unsafe Credentials
Hard-coded credentials leak into prompts and code
MFA Breaks Everything
Multi-factor authentication stops most automation dead
