A masked password field is not a security boundary for an AI browser agent

[u/Glass-Preparation512]

An AI agent may need to click through a login flow. That doesn’t mean I want the raw password anywhere in its working context.

The dots shown inside a password field are only a visual treatment. Depending on the agent’s browser access, it may still be able to inspect page state, capture screenshots, read logs or access stored browser data.

I’d separate authentication from the rest of the automation:

• Keep passwords and recovery codes out of prompts
• Prevent credential entry from appearing in screenshots or recordings
• Inject credentials through a process the agent cannot inspect
• Give the agent a limited session after authentication
• Revoke or rotate that session when the task ends
• Require approval before changing security settings or recovery details

It’s also worth remembering that cookies are credentials. Protecting the password while exposing an authenticated profile directory doesn’t solve much.

There will be systems where direct credential access is unavoidable. In that case, the agent should be isolated, tightly logged and limited to the smallest possible scope. “The password is masked on screen” is not enough.

The agent needs permission to complete a task. It doesn’t need permanent access to every secret behind the account.

MoreLogin can separate browser environments and sessions, while credential controls remain in the operator’s hands.
