Losing a hardware wallet does not automatically mean losing your bitcoin. With a usable wallet backup—and the correct passphrase, if you set one—you can usually restore access on a compatible device. Losing every way to recover the keys is a different problem.
This guide covers a standard, single-signature self-custody wallet. Multisignature and shared-backup arrangements have their own recovery requirements.
THREE THINGS. THREE DIFFERENT JOBS.
BITCOIN NETWORK
Your bitcoin is recorded on the blockchain.
HARDWARE WALLET
Holds keys and signs transactions.
WALLET BACKUP
Lets you reconstruct access—not reverse a theft.
Start with what you still have
Do not reset a working device while you are uncertain about its backup. First identify your situation:
| Situation | What matters now |
|---|---|
| Device lost; backup available | Use the manufacturer’s recovery instructions for a compatible replacement. A missing device may be a security risk. |
| Backup lost; device still works | Preserve access. Plan migration to a newly backed-up wallet before wiping anything. |
| Device and backup both lost | Without another valid recovery route, access may be permanently lost. A transaction ID cannot recreate keys. |
| Backup may have been copied | Treat the wallet as compromised. Replacing only the device does not replace its keys. |
Trezor’s missing-device guidance describes recovery and migration for these situations. Follow the instructions for your exact model; this table is a triage aid, not a device-specific recovery procedure.
A PIN is not a wallet backup
A PIN protects access to a device. A recovery backup reconstructs a wallet. An optional passphrase changes which wallet you access; the backup alone is not enough for a passphrase-protected wallet. Check the manufacturer’s backup and recovery documentation before starting.
Two examples that make the distinction clear
Example A: Maya drops her device in water. Her backup remains readable and private, and she knows her passphrase. The broken device is replaceable; recovery depends on those credentials and a compatible wallet.
Example B: Leo buys a replacement device and restores a backup that someone else has photographed. He has restored the same keys. The new hardware has not removed the other person’s access. These are illustrative scenarios, not customer cases.
Make a recovery plan before you need one
Keep the backup protected from both loss and unauthorized access. Consider hazards that could affect the device and its backup at the same time. Bitcoin.org’s wallet-security guide explains backup, storage and inheritance considerations.
Record non-secret recovery instructions separately: device model, official documentation location, backup format and whether an additional passphrase is required. Do not put the secret words into this checklist. Use the manufacturer’s built-in backup-check feature where available; do not wipe your only working wallet just to test yourself.
Do you need to buy another wallet?
A replacement may be useful when the original device is gone or unusable. It cannot compensate for missing recovery credentials. Before comparing products, establish what backup format you have and which devices support it. Buying first does not solve the recovery question.
