What should you keep out?
Secrets and credentials
Do not expose API keys, access tokens, passwords, private keys, or credential files. OWASP specifically identifies patterns such as .env, .env.*, *.pem, *.key, credentials.json, and serviceAccountKey.json as files to protect. Its guidance is to store secrets in environment variables, vault services, or encrypted secret stores rather than in files inside the project tree an AI tool may read. See the OWASP Secure Coding with AI Cheat Sheet.

Personal, customer, and regulated data
Keep customer records, personal information, and regulated data out unless the organization has explicitly approved the tool and the processing path for that data. A tool’s general availability or a user’s access to it does not establish that a particular data type is permitted.

Proprietary business logic, private source code, internal architecture, and customer-owned code can be sensitive even when they contain no credentials or personal information. Check company policy and contractual obligations before sharing them with an external model.
#1 Best Overall
- Cut Repetitive Keystrokes Down to One Press: Built with 3 mechanical keys and multi-mode switching, this keypad lets developers trigger AI prompts, commands, and macros for Claude Code, Cursor, Codex, and other AI coding assistants without leaving the keyboard — switch modes to access 9+ custom shortcuts from the same 3 keys.
- Voice Input That Stays Clear Wherever Your Keypad Sits: Unlike keypads with a microphone built into the body, ours detaches and clips onto your collar so it stays close to your mouth no matter where the keypad sits on your desk. An onboard DSP chip with intelligent noise reduction and ~30ms latency keeps dictated code comments and voice commands accurate, even with keyboard noise or office chatter in the background.
- Built to Fit Your Existing Setup, Not Replace It: Connects via Bluetooth 5.4 or the included USB-C receiver and works across Windows, Mac, and Linux, so the same unit runs on every machine your team uses. It's designed as a dedicated shortcut and dictation companion that sits alongside your primary keyboard, not a replacement for it.
- Reprogram It for How You Actually Work: Use the companion app to record macros and remap all 3 keys per mode — one profile for AI assistant commands, one for IDE actions, one for your own custom sequences. Built for solo developers working late and teams running multiple AI tools side by side.
- PWhat's in the Box: Includes 1x multi-mode macro keypad, 1x detachable clip-on microphone, 1x USB-C receiver, 1x furry windshield, 2x USB-C cables, and 1x user manual. Built-in 380mAh battery charges via the included USB-C cable; wall adapter not included.
What might an AI coding tool receive?
The relevant boundary can extend beyond text deliberately pasted into a prompt. Depending on the product and settings, context may include open files, project structure, indexed repository content, and terminal output. OWASP describes coding assistants as sending code context such as open files, project structure, and terminal output to a model provider’s API (OWASP guidance).
Agents can have a broader reach than completion or chat features. An agent may read repository and external content, execute commands, edit files, call APIs, or use connected tools such as MCP servers. The practical risk therefore depends both on the content available and on the permissions granted to the agent.
Rank #2
- HARDWARE 2FA AND MFA: FIDO Alliance Certified FIDO2 v2.1 with CTAP2 plus legacy U2F and CTAP1 for strong two-factor login and passwordless sign-in on services that support security keys
- BUILDING ACCESS ON ONE CARD: MIFARE DESFire EV2 4K applet with AES encryption adds office door and physical access control alongside digital authentication
- CERTIFIED SECURE ELEMENT: An NXP Common Criteria EAL6+ certified secure controller and Java Card platform protects your keys on a tamper-resistant chip
- DUAL INTERFACE SMART CARD: Contactless NFC ISO 14443 plus ISO 7816 contact reader support in an ISO 7810 ID-1 format that is passive and needs no battery
- SWISS ENGINEERED DESIGN: Built by Cryptnox as a single card for authentication and access control and backed by a 2 year warranty
How to set a safe boundary
- Identify the material. Check for credentials, personal or regulated information, proprietary business logic, sensitive architecture, and customer-confidential content.
- Map the data path. Find out what the editor, chat feature, repository indexing, prompts, terminal output, agent tools, connected services, and selected model provider can access.
- Review the exact product and account. Read the vendor’s documentation and your organization’s rules for context collection, exclusions, retention, model-training use, processing location, and administrative controls. These details can differ by product, plan, account settings, geography, and model provider.
- Configure exclusions in the AI tool itself. Exclude sensitive files and directories using the product’s supported controls. Do not assume
.gitignoreprevents an AI tool from reading a file: Git ignore rules govern version control, not necessarily filesystem access by another application. - Keep credentials out of the working tree. Use approved environment-variable, vault, or encrypted-secret mechanisms. Do not put long-lived or production credentials in prompts, agent environments, or project configuration files.
- Restrict agent permissions. Grant only the filesystem, shell, network, and connected-tool access needed for the task. Where credentials are necessary, use scoped, short-lived credentials and require human review before consequential actions or security-sensitive code changes.
- Escalate uncertainty. If the policy or data-handling terms are unclear, stop and ask the organization’s security or privacy owner before exposing the material.
When should you use an approved or isolated tool?
For classified, regulated, or otherwise highly sensitive work, follow organizational policy and use an explicitly approved deployment. OWASP recommends self-hosted or air-gapped coding tools for high-sensitivity work; see its IDE and AI-Assisted Development Security guidance. An isolated deployment is not automatically sufficient on its own: the organization still needs to approve its configuration and the data flow.
How to compare tools before using them
A label such as “private” or “safe” does not answer the practical questions. Compare the specific tool, account, and model provider on these points:
Rank #3
- FIDO2 CERTIFIED: FIDO Alliance Certified FIDO2 v2.1 and CTAP Level 1 for 2FA and MFA on Google Microsoft Apple GitHub login.gov AGOV SwissID and any WebAuthn service
- PASSKEY READY: Works as a hardware passkey for passwordless sign-in where the service enables it and as a U2F and WebAuthn security key everywhere else
- CERTIFIED SECURITY: NXP JCOP 4.5 secure element rated Common Criteria EAL6+ (augmented)
- TAP OR INSERT: Dual NFC ISO 14443 and contact ISO 7816 interface in an ID-1 format smart card that is passive and battery-free
- BUILT TO LAST: Passive smart card made in Switzerland designed by Swiss company Cryptnox and backed by a 2 year manufacturer warranty
- Context: What files, project information, prompts, completions, and terminal output can be collected, and how can they be excluded?
- Retention and training: How are prompts, responses, and sessions retained or used for model training?
- Processing: Where is data processed, and which provider receives it? For example, GitHub says that with BYOK, prompts and responses are transmitted to the selected provider and may be subject to that provider’s retention and privacy policies (GitHub Copilot Chat responsible-use documentation).
- Agent permissions: Can the tool read or change files, run shell commands, use the network, or call connected services? What limits and approval steps are available?
- Governance: Can administrators control use, review activity, or audit relevant settings, and is the organization’s approved configuration in place?
For GitHub Copilot-specific security, governance, and network controls, consult GitHub’s security, governance, and network settings documentation. For agent and MCP risks, see the OWASP AI Agent and MCP Security guidance. These references do not establish that every vendor or plan behaves the same way; verify the product and account you actually use.
