How to change Trezor device name? (Personalization)

Accessing Device Settings via Trezor Suite

1. Launch the latest version of Trezor Suite desktop application or web interface using a supported browser such as Chrome or Edge.

2. Connect your Trezor Model T or Trezor One device and enter the correct PIN to unlock it.

3. Navigate to the Settings tab located in the left-hand sidebar after successful connection.

4. Under the Device section, locate the field labeled Device name.

5. Click the pencil icon next to the current name and input a new identifier consisting of alphanumeric characters only.

Constraints on Custom Naming

1. The maximum allowed length for a Trezor device name is 24 characters.

2. Special symbols including @, #, $, %, &, *, /, \, and spaces are explicitly prohibited.

3. Unicode characters outside the ASCII range—such as accented letters or emojis—are not accepted by the firmware.

4. Names are case-sensitive but do not affect functionality or security parameters.

5. Duplicate names across multiple Trezor devices connected to the same host will not trigger errors but may reduce identification clarity during multi-device workflows.

Firmware-Level Validation Process

1. Upon submission, the Suite sends the updated name string directly to the device’s secure microcontroller.

2. The firmware performs internal validation against character set and length rules before accepting the change.

3. No network call or remote verification occurs—the operation is fully offline and deterministic.

4. If validation fails, the UI displays an immediate red error message without modifying stored values.

5. A green success banner appears only after the device confirms persistent storage of the new name in its non-volatile memory.

Impact on Third-Party Integrations

1. Block explorers and wallet interfaces like bloks.io or Scatter display the device name only when used in conjunction with specific dApp permissions.

2. EOS account creation flows rely solely on public key derivation—not device naming—for identity binding.

3. Ethereum-based sign requests show the Trezor model identifier (e.g., “Trezor Model T”) regardless of custom naming.

4. Multi-signature configurations involving Trezor co-signers retain full compatibility even if device names differ across participants.

Frequently Asked Questions

Q: Does changing the Trezor device name require firmware update?No. Name changes operate independently of firmware versions and function correctly on all supported releases from 2.4.0 onward.

Q: Can I revert to the default name after customization?Yes. You may manually re-enter the original factory-assigned name—typically “Trezor” followed by last four digits of the device ID—as long as it complies with current naming rules.

Q: Will renaming affect backup seed phrase recovery?No. The seed phrase remains entirely decoupled from device naming. Recovery operations ignore any stored name value.

Q: Is the device name visible to websites during hardware signing?No. Websites never receive the device name during transaction signing or address derivation; only cryptographic signatures and public keys are transmitted.
