This article describes the different options of using the Trezor device with Android.


NoteThis page applies to Trezor Model T (show for Trezor One).


With the release of our Trezor Manager application for Android, we have introduced an alternative method of setting up, customizing, and recovering your Trezor device even without a computer. It should work on all Android devices that support USB Host. You need an OTG cable to connect the Trezor to your phone or tablet. Currently, the app can only be used to initialize the device, recover the device, set up the PIN code and passphrase, and some other functionalities. You can download the Trezor Manager app from Google Play. Alternatively, you can download it as a binary APK, or see the source code at Github.

To make payments with Trezor via your phone, it is possible to connect to Trezor Wallet in your browser using WebUSB.

You can also install a third-party application, e.g., Mycelium.


Trezor Wallet with WebUSB[edit]

You can connect to Trezor Wallet directly using WebUSB. Just plug your Trezor in to your Android phone, open Google Chrome, and visit beta-wallet.trezor.io. Everything else works just like when using Trezor Wallet on a desktop computer.


NoteConnecting via WebUSB on an Android phone is available for Trezor Model T and for Trezor One starting from firmware 1.7.0.


Using Android with Trezor Beta Wallet[edit]

Trezor Beta Wallet (beta-wallet.trezor.io) is a less-tested version of the web-wallet. New features are released here first before we consider them sufficiently reliable for the production wallet. It serves as a public feature-testing platform for the Trezor community, providing power users with quick access to new features.

1. Connect your Trezor device and visit https://beta-wallet.trezor.io in Google Chrome.

2. Selecting the Menu button in the top left corner you can switch cryptocurrencies and accounts.


3. By selecting the Transactions dropdown menu you can switch to the Receive, Send, Exchange, or Sign & Verify tabs and use the Trezor Beta Wallet in the same way as using it on your computer.


Trezor setup with Trezor Manager[edit]

First Look[edit]

Trezor Manager for Android

Download and install the application from Google Play. Open the app and then plug in your Trezor with an OTG cable. The device should prompt you to allow USB access. In case you have initialized your Trezor previously, enter the PIN and access the home screen of the app.

Initialize Your Trezor[edit]

If your Trezor is new, the app starts the setup process. It is very similar to Trezor setup with a desktop computer.

Setting up a PIN[edit]

The PIN follows Trezor security standards — the position of numbers on the PIN pad is randomized. Enter the PIN using the touchscreen of your Trezor device. The PIN matrix changes every time there is a new PIN prompt.

Setting up the recovery seed[edit]

After you set your new PIN, write down the recovery seed. Seed words are displayed on your Trezor device. Remember to write down all the words and store them in a secure place. The recovery seed represents your master key. If you lose access to it, it will be impossible to recover your funds if your Trezor device is stolen or damaged. Additionally, if someone steals your recovery seed, they will have full access to your account. Read more about the recovery seed and its security in our blog post Learn about: Recovery seed.

Seed Recovery[edit]

The Android app also supports the recovery of your Trezor. The process is simple, as the app guides you step by step until you finalize the initialization. Please follow each step carefully. Have your recovery seed ready. The order of the words is shuffled, as is standard for Trezor security practices.

Wipe and update firmware[edit]

You can also easily wipe an initialized device with Trezor Manager. The option is available directly on the home screen.

Updating the firmware is the same as on a desktop computer. Start swiping your finger across the Trezor touchscreen and plug in the USB cable when your finger is halfway through. Once connected in bootloader mode, confirm the connection on your device. You can see the process illustrated in this short clip. The phone should automatically offer you an update to the firmware.

Trezor with third-party services[edit]

When using an Android mobile device, you can also choose one of the available third-party services, such as Mycelium, Sentinel or Walleth. For more information, see the relevant articles. For more information about third-party services, see Trezor Apps.
