Trezor recovery: lost PIN, forgotten passphrase, broken device

A Trezor One or Trezor Model T is just a vault for your 12 / 18 / 24-word seed. If you have the seed written down, the device itself is replaceable — any BIP39-compatible wallet can restore it. The hard cases are the ones where the seed and the device are both partially lost: a PIN you can't remember on a device whose seed backup you misplaced, or a 25th-word passphrase you set years ago and never wrote down. Here's the honest playbook for each.

Never type your seed or passphrase into a website, even one calling itself a "Trezor recovery service". Trezor will never ask for your seed. Neither will we — until we're under NDA and the work runs on equipment you control or observe.

You have the seed, just not the device

Easiest case. Buy a new Trezor (or any BIP39 hardware wallet) and run "Recover wallet". Enter the seed in the order Trezor prompts. If you'd used a 25th-word passphrase, you'll need that too — see below.

Forgotten PIN, seed in hand

The PIN protects the device, not the funds. Wipe the Trezor (Settings → Device → Wipe) and recover from the seed. You'll set a new PIN during setup. If you can't reach the Wipe menu because the device is PIN-locked, enter wrong PINs 16 times — the Trezor will reset itself.

Forgotten 25th-word passphrase

A BIP39 passphrase ("the 25th word") creates an entirely separate wallet from the same seed. There's no list to choose from — it can be anything. If you forget it, the seed alone restores an empty wallet, which is why people panic and assume the funds are gone. They aren't. The standard recovery path:

Write down everything you remember: rough length, language, any capitalization or symbol you tend to use, any phrase you were "into" the year you set up the Trezor.
Note the first receive address you remember seeing — even a screenshot or a tx in a block explorer is enough to confirm a candidate.
Run an offline BIP39 passphrase search (btcrecover supports this) against your seed, targeting that known address. The right passphrase derives that address; everything else doesn't.

This is the single most common Trezor case we work. It's slow and methodical, but it's a finite search — if the passphrase is short or thematic, modern GPUs find it.

Physically broken or "bricked" device

If the screen is dead but you have the seed, the device doesn't matter — recover into a new one. If the device is damaged AND you've lost the seed backup, the funds are not on the chip in a form anyone can pull off. Trezor's seed is generated inside the device and is only stored as the words you wrote down. Anyone advertising "chip-off Trezor recovery" with no seed is selling you something that doesn't exist. We'll tell you that for free.

Partial seed (a word or two missing)

BIP39 seeds have a checksum, so if a word is missing or wrong, restoration just fails — but a brute force across one or two unknown words is fast (a few minutes on a laptop). For 11 of 12 words or 23 of 24, success is the norm. Past that, it gets exponentially harder; bring in help before you burn out trying.

When to call us

The Trezor cases that benefit most from a specialist:

Forgotten BIP39 passphrase where you have the seed and a known address.
Seed where two or more words are illegible from water, fire, or fade damage.
Restored wallet that shows zero balance even though you can see prior transactions on chain.
Suspected typo or swapped words in a written backup.
