AI web agents perform human-like browsing tasks but cannot authenticate without workarounds like cookie syncing from Chrome profiles, password manager integration such as 1Password, TOTP code generation from secret keys, and agent-managed email inboxes for verification codes.

Browser Use enables these via terminal commands, Python code for profile syncing or storage export, and placeholders for sensitive data injection. These methods allow agents to access personal services like email and calendars securely today.
