Trezor @Login – The Official Wallet

About hardware wallet login and security (overview)

Hardware wallets provide a strong, isolated environment for storing private keys. When you "log in" with a hardware wallet, the device signs transactions and responses inside a secure chip; the private keys do not leave the device. The web interface acts only as a conduit for user prompts, address display, and transaction construction — it should never request or collect your seed phrase or raw private keys.

Typical workflow

1. Connect: The user connects the hardware wallet to their computer or phone (USB, WebUSB, Bluetooth, or scanning a QR code for some models). The site detects the device and displays its status.
2. Approve: For sensitive operations — such as exporting an address, signing a transaction, or changing settings — the device will show the details on its own screen. The user must physically approve actions by pressing the device button(s).
3. Sign: The device returns a cryptographic signature to the host; the private key remains protected inside the device.
4. Broadcast: The web app or wallet software submits the signed transaction to the network.

Best practices and safety tips

• Always verify the device screen: Confirm addresses and amounts on the hardware device’s display before approving. Attackers can attempt to trick you with altered host displays.
• Never enter your recovery seed into any website or browser: Recovery seeds are single points of failure; only enter them into the device during secure, offline setup.
• Keep firmware up to date — but only update from official sources. Verify firmware signatures and release notes from the manufacturer's official channels.
• Use a strong device PIN and enable passphrase features only if you understand them. A passphrase can act as an extra secret, but losing it means losing access to funds.
• Keep a secure, offline backup of your seed in physical form (metal backup if possible) and store backups in separate secure locations.
• Be cautious with browser extensions: Only use trusted wallet interfaces. Browser extensions or unknown apps can attempt to intercept or trick key requests.

What a safe web login page should never do

• Request your recovery phrase.
• Ask you to paste private keys.
• Automatically export private keys without explicit device confirmation.
• Run arbitrary scripts that attempt to bypass device UI confirmation steps.

If you suspect compromise

If you suspect your computer or browser has been compromised, do not connect your hardware wallet. Use a clean, offline device to access your funds or use a trusted environment. If you believe a seed has been exposed, move funds using a clean device and a new seed as soon as possible.

Developer notes (safe integration)

Developers integrating hardware wallets should rely on standard APIs (WebUSB, WebHID, Bluetooth) and follow vendor SDKs and best practices. Ensure that the web UI never logs or stores sensitive information and always surfaces the device's on-device messages to the user. Use TLS, Content Security Policy (CSP), and Subresource Integrity (SRI) for static resources.
