How to set up Trezor on Android mobile without a computer

Trezor is a hardware wallet used to store the private keys of cryptocurrencies. This article describes how to set up your Trezor device via a web browser on an Android smartphone, without needing a computer or the Trezor Suite Lite app, which is the recommended method for initial setup.

Important: The initial Trezor setup must be done exclusively through the Chrome web browser. It cannot be performed using the Trezor Suite Lite app. Recommendation: Do not download the Trezor Suite Lite app until the wallet's initial setup is complete.

Summary

Important: Trezor setup must be done only via the Chrome web browser on an Android phone. It cannot be done through the Trezor Suite Lite app.

Steps for using Trezor without a computer:

1. Initial setup: You must use the Chrome web browser on your phone to set up a new device. Go to suite.trezor.io to create your recovery seed and set your PIN.
2. Daily Use: After setup is complete, you can choose to use the Trezor Suite Lite App for convenient daily use, or continue using the Chrome web browser.

 

The advantage is that both methods allow firmware updates directly on the mobile device. Although there are some limitations compared to computer usage, it is convenient for users who do not have a computer or wish to carry and use their hardware wallet while traveling.

The most crucial thing is to keep your recovery seed safe to ensure your digital assets are protected in the best possible way.
