Safety, privacy and control
Understand the boundaries around Muse’s workspace, connected accounts and actions.
These controls describe Meta’s Muse product where documented. Local models, custom tools and third-party integrations may have different security boundaries.
Your workspace
Muse performs work inside a separated environment. Isolation limits the workspace’s reach; configured connections and permissions still matter.
How isolation works
Meta describes Muse Secure VM as a persistent, isolated Linux computer with a full browser that you and your agent can use together. You can intervene at any point. The September launch announcement described Confidential VM as a future feature; do not assume current Secure VM data is inaccessible to Meta.
Your accounts
A credential service can authorize an account connection without handing the underlying secret to the model.
Privacy and connected accounts
Meta says you can disconnect services, opt out of consumer interactions being used for model training, and ask Muse to forget saved information. Logins live in a secure credential store the agent cannot read. For shopping, one-time card numbers can be used so the real card is never exposed to the merchant or the agent.
For developers, Standard API prompts and completions are not used for training. Contributor requests permit training in exchange for lower prices. Neither statement alone establishes zero retention; check the selected service’s terms.
Your approval
Sending a message, making a purchase or sharing information can require a decision from you before the action proceeds.
How approvals work
Muse is designed to ask before actions such as sending messages, making purchases or sharing information with connected apps. Users can allow once, always allow or deny, and review activity and previously approved permissions.
Outside information
A webpage or document can contain hostile instructions. Reading that content should not give it the authority to act on your behalf.
How outside content is treated
Prompt injection is not solved. Meta's approach combines classifiers, permission isolation, restricted credentials and human approvals rather than relying on the model alone.
A webpage asks for your private files.
The page is information Muse encountered. It is not permission from you to share private data.

- 2Check the requested action
- 3Restrict or request approval
These controls reduce risk, but no agent system can eliminate every security problem.
