How to Authenticate AI Web Agents

AI web agents often struggle with authentication, which prevents them from completing useful tasks that require a user to be logged in. This guide outlines several methods to solve this, including cookie syncing, where an agent's browser inherits a user's login cookies to maintain an authenticated session. Another approach involves integrating with password managers like 1Password, allowing agents to securely retrieve and fill credentials without direct access to the passwords. The content also details how to handle two-factor authentication (2FA) by programmatically generating TOTP codes or managing verification codes sent via email and SMS, comparing how different platforms implement these solutions.
