How do I connect my Trezor to my phone?

Connecting Your Trezor to a Mobile Device

1. Begin by ensuring your Trezor device is updated with the latest firmware version available from the official Trezor website. This guarantees compatibility with mobile applications and enhances security features during the connection process.

2. Install the Trezor Suite Lite app from the Google Play Store if you are using an Android device, or from the Apple App Store for iPhone users. This application acts as the interface between your hardware wallet and smartphone.

3. Use a compatible USB OTG (On-The-Go) cable to physically connect your Trezor Model T or Trezor One to your phone. The OTG adapter allows your smartphone to act as a host for external devices like your Trezor.

4. Once connected, unlock your Trezor by entering your PIN directly on the device’s screen. This step ensures that no sensitive data is exposed through the phone’s interface.

5. Open the Trezor Suite Lite app and follow the on-screen prompts to establish a secure session. The app will recognize your device and allow access to view balances, receive crypto, and sign transactions offline.

Supported Cryptocurrencies and Wallet Management

1. The Trezor mobile integration supports a wide range of cryptocurrencies including Bitcoin, Ethereum, Litecoin, and over 1,000 ERC-20 tokens. You can manage multiple wallets within the same interface without switching devices.

2. Within the app, generate new receiving addresses for each coin type. These addresses are derived from your seed phrase and remain consistent across devices when restored properly.

3. To send funds, initiate a transaction in the app, confirm the recipient address and amount, then approve it on your Trezor’s display. This two-step verification prevents man-in-the-middle attacks.

4. Transaction signing occurs entirely on the Trezor hardware, meaning private keys never leave the device—even when linked to a mobile phone.

5. For added convenience, you can pair the Trezor with both mobile and desktop versions of Trezor Suite using the same recovery seed, enabling seamless cross-platform management.

Security Best Practices During Mobile Connection

1. Always verify the authenticity of the Trezor Suite Lite app before installation. Only download it from official app stores to avoid counterfeit apps designed to steal credentials.

2. Ensure your phone is free from malware by running regular security scans and avoiding rooted or jailbroken systems, which compromise app sandboxing protections.

3. Never enter your recovery seed into any mobile application. The seed should only be used during device setup or recovery, and always inputted directly on the Trezor screen.

4. Disconnect your Trezor immediately after completing transactions. Leaving it plugged in increases exposure to potential physical or digital threats.

5. Enable passphrase protection if you use advanced account segregation. This feature adds an extra layer of control, requiring a secondary word or phrase to access specific wallet configurations.

Frequently Asked Questions

Can I connect Trezor to an iPhone wirelessly?No, current models do not support Bluetooth or Wi-Fi connectivity. iPhones require a Lightning to USB adapter along with a standard USB A-to-Micro B cable for Trezor One, or USB-C for Trezor Model T.

Is it safe to use third-party wallets with Trezor on mobile?Only wallets officially integrated with Trezor, such as Trust Wallet or Exodus when paired via WalletConnect, are considered safe. Direct USB support remains limited to Trezor Suite Lite.

What should I do if my phone doesn’t detect the Trezor?Check that the OTG cable is functioning, restart the phone, ensure USB debugging is disabled, and confirm that the Trezor firmware is up to date. Some budget Android phones lack full OTG support.

Does connecting to a phone expose my private keys?No. Private keys are stored exclusively on the Trezor device. Transactions are signed internally, and only public data such as balances and addresses are shared with the mobile app.
