On June 25, 2026, Anthropic shipped Trusted Devices for Claude Code Remote Control — a beta feature for Team and Enterprise plans that requires device verification before any member can view or steer a local session from a browser, phone, or desktop app.
This is a meaningful security addition. Remote Control is useful — it lets developers continue a local session from their phone or a browser without moving any code to the cloud. But “your local filesystem, MCP servers, and tools, accessible from any signed-in device” is also a wide attack surface. Trusted Devices tightens that surface.
The problem Trusted Devices solves
Claude Code Remote Control runs on your machine. Your local environment — filesystem, credentials, MCP servers, configured tools — stays local. The web or mobile interface is a window into that session, not a copy of it.
The threat model for a signed-in-account-only system is account compromise. If an attacker phishes a developer’s claude.ai credentials, or if a developer logs in on a shared machine and walks away, the attacker has full access to steer whatever Claude Code session is open — including running arbitrary Bash commands on the developer’s local filesystem.
Trusted Devices adds a second factor that’s tied to a specific physical device, not just credentials:
- Enrolled device: each browser, phone, or desktop app registers its own credential during a deliberate enrollment step linked to a real sign-in
- Recent authentication: the member’s session must be less than 18 hours old, confirmed via biometric step-up (Face ID, Touch ID, Windows Hello, or a passkey)
Account credentials alone cannot access a Remote Control session. The attacker also needs a device that was previously enrolled by the developer.
How enrollment works
Enrollment is intentionally non-silent. The first time a member tries to view or steer a Remote Control session on a new device, they must enroll that device. The enrollment prompt only appears after a full sign-in — not in the background and not automatically.
Day to day, most members see no prompts. When the 18-hour window expires, the next Remote Control interaction triggers a single biometric step-up. On mobile that is Face ID or a fingerprint; on desktop it is Windows Hello or a passkey. The check happens locally on the device; Anthropic receives only a public key and metadata (device name, platform, enrollment date). Fingerprints and face data never leave the device.
The machine running Claude Code itself enrolls automatically when the developer signs in via the CLI (/login). No separate enrollment step is needed in the terminal.
What Trusted Devices does and does not cover
Covers:
- Viewing a Remote Control session from claude.ai/code in a browser
- Steering a session from the Claude iOS or Android app
- Connecting from Claude Desktop to a Remote Control session
Does not cover:
- Regular Claude chat (web or app)
- Claude Code in the terminal (local process is unaffected)
- API usage
- Claude Code on the web (those sessions run in Anthropic’s cloud, not Remote Control)
The setting is binary: on or off for the entire organization. Per-team or per-project scoping is not available in this beta.
How to enable it
Requirements: Team or Enterprise plan, Owner access to the admin console.
- Go to
claude.ai/admin-settings/claude-code - Find Require trusted devices under the Remote Control section
- Toggle it on
The setting applies immediately to new Remote Control sessions. Sessions that were already running before you enabled it are not retroactively protected — they continue without the device requirement until they end naturally.
Warn your developers before enabling. The first time a developer tries to use Remote Control from a browser or phone after the toggle is on, they will be asked to enroll that device. Unexpected enrollment prompts cause confusion; a heads-up prevents support tickets.
One edge case: if the admin toggle appears grayed out, the organization has a data retention or compliance configuration incompatible with Remote Control. This cannot be changed from the admin panel; contact Anthropic support.
Managing enrolled devices
Members manage their own devices. From claude.ai/settings/account, the Trusted devices section lists every enrolled device with its name, platform, and enrollment date.
Removing a device revokes its credential immediately. The device can re-enroll later after a fresh sign-in. Credentials also expire automatically when not renewed, so a device that has not been used drops off the list on its own.
For a lost or stolen device: the member removes it from account settings. If the member cannot sign in, an admin can use Sign out everywhere in the admin console to revoke every session and enrolled device for that account. The developer then re-enrolls their remaining devices.
When to enable it
Enable Trusted Devices if:
- Developers on your team use Remote Control regularly from phones or browsers
- Your organization’s risk posture treats developer workstations as high-value targets (which, given that they have filesystem and credential access, they are)
- You have developers who work from shared machines, shared browsers, or travel with shared-device environments
Skip it or wait if:
- Your team has not adopted Remote Control yet — Trusted Devices adds friction to a feature your developers are not using
- You are still evaluating Remote Control and want to reduce onboarding surface
The beta designation means the experience may change. The security model (device enrollment + biometric step-up) is stable, but the admin UI, the enrollment flow, and per-team scoping are all areas that Anthropic is likely to refine.
The broader Remote Control security picture
Trusted Devices is the most visible security addition, but it sits on top of a few other design choices worth noting:
No inbound ports. Claude Code makes outbound HTTPS requests only. Your machine never accepts inbound connections. The Anthropic API routes messages between the web/mobile client and your local session over TLS. An attacker on your network cannot reach the session directly.
Short-lived credentials. The connection uses multiple short-lived credentials, each scoped to a single purpose and expiring independently. A leaked credential cannot be reused indefinitely.
Sandboxing is optional. Remote Control works with --sandbox mode, which limits filesystem and network access for commands Claude runs. This is separate from Trusted Devices but complementary: Trusted Devices controls who can steer the session; sandboxing limits what that steering can do.
The most direct remaining risk is session hijacking after enrollment — if a developer leaves an enrolled phone unlocked, anyone with physical access can interact with an active session. That risk exists in any biometric system and is the tradeoff for low-friction daily use.
