If you have searched for "recover Ledger PIN" or "bypass Trezor PIN", you have almost certainly landed on blogs and YouTube videos promising miracle tools. They are scams, without exception. Hardware wallets are specifically designed to make PIN recovery impossible — that is the entire reason they exist. This guide explains why, and what your real options are.
- Forgotten PIN + have seed phrase → fully recoverable. Reset device, restore from seed.
- Forgotten PIN + no seed → funds lost. No exceptions.
- Broken device + have seed → fully recoverable. Buy any BIP39-compatible wallet, restore.
- Lost device + have seed → same as above.
- Lost or forgotten seed + device works → funds accessible now, but you must migrate to a new seed immediately.
Why the PIN is not recoverable
Hardware wallets split functionality between two chips:
- A general-purpose MCU (STM32 or similar) that handles USB, the screen, and button input.
- A secure element (Ledger uses ST33 / ST31, Trezor Safe 3 uses OPTIGA Trust M) that stores the seed and verifies the PIN.
The PIN never leaves the secure element. When you type it, the MCU passes the candidate PIN into the SE, which runs a constant-time comparison against the stored hash. Wrong attempts increment an internal counter — after the threshold (3 for Ledger, 16 for Trezor), the SE wipes the seed storage. This counter cannot be reset by external means because there is no external interface that can read or write it.
Extracting the seed from the SE requires breaking the secure element itself, which is exactly what vendors like Rambus, Riscure, and various national labs spend millions on. Even when successful, attacks cost five-figure budgets per device and apply to specific firmware versions.
The seed phrase — your actual backup
Every modern hardware wallet shows you a 12, 18, or 24-word BIP39 seed phrase during initial setup. This phrase is the complete and only backup of your wallet. The device itself is just a signing computer; it can be replaced with any BIP39-compatible wallet.
| Device | Seed length | Standard | Optional passphrase |
|---|---|---|---|
| Ledger Nano S / S Plus / X | 24 words | BIP39 | Yes (hidden wallets) |
| Trezor One | 12, 18, or 24 words | BIP39 | Yes (hidden wallets) |
| Trezor Model T / Safe 3 / Safe 5 | 12, 18, or 24 words | BIP39 or SLIP-39 Shamir | Yes |
| Keystone Pro / Essential | 12 or 24 words | BIP39 | Yes |
| Coldcard Mk4 / Q | 12 or 24 words | BIP39 | Yes (tap-n-go) |
Step-by-step: restore a Ledger from your 24-word seed
- If your existing Ledger is locked and you accept losing its state, let it wipe itself by entering 3 wrong PINs. Or buy any BIP39-capable wallet (another Ledger, a Trezor, a software wallet).
- On the clean/new device, select "Restore from recovery phrase" during setup.
- Enter your 24 words in the correct order. The device validates the BIP39 checksum — if a word is wrong or out of order, it will reject.
- Set a new PIN.
- Install the coin apps (Bitcoin, Ethereum, etc.) via Ledger Live / Trezor Suite.
- Your addresses reappear; your balances are visible; you can sign transactions.
Partial seed? Missing a word?
If you have most of your seed but lost one or two words, or you suspect a typo, there is genuine hope: seedrecover.py from btcrecover can iterate the missing words, verify each candidate against a known address, and find the correct seed. 1–3 missing words is routinely recoverable; 4+ missing words needs substantial narrowing constraints. See our BIP39 seed recovery guide for details.
Trezor voltage-glitch attack — history only
In 2019, researchers at Kraken Security Labs demonstrated a hardware fault-injection attack on the Trezor One. By momentarily glitching the power supply at a precise microsecond during boot, they bypassed the SRAM protection of the STM32F205 and dumped the encrypted seed. This made headlines, but the details matter:
- Required physical possession of the device for several hours.
- Required a soldering rework and specialised lab equipment (arbitrary waveform generator, triggering logic).
- Yielded only the encrypted seed blob — still needed the wallet passphrase (if set) to decrypt.
- Patched in Trezor Model T (uses a different MCU + secure element hardware architecture) and later Trezor Safe line.
Some recovery services on Reddit and Telegram claim to perform this attack commercially. If you own a Trezor One that was not wiped and you have exhausted all other options, technically such a service could be real. In practice, 99% of listings are scams, and the legitimate operations charge $3,000–$10,000 per attempt with no guarantee. This is not a mainstream recovery path.
- Anyone promising to recover any hardware wallet PIN without physical device access.
- "Specialists" asking you to send your recovery phrase to verify "device compatibility".
- Services quoted in advance as a flat fee with "guaranteed success".
- Services that ask you to install custom firmware / an "unlocker app".
Ledger Recover — the controversial opt-in
In May 2023, Ledger launched Ledger Recover, a paid subscription service that splits your seed into three cryptographic shards using a Shamir-style scheme and distributes them to three independent custodians: Ledger, Coincover, and EscrowTech. Subscribers can recover their seed by passing ID verification with two of the three custodians.
Community reaction was overwhelmingly negative because:
- It requires the Ledger device firmware to be able to export the seed in encrypted form, contradicting the long-held marketing that "your seed never leaves the device".
- It introduces a KYC layer to self-custody.
- Users must trust three centralised entities.
On the other hand, it is opt-in. Devices that do not enroll behave exactly as before. If you have not subscribed, Ledger Recover has no effect on your wallet. As a recovery path, it is useful only if you are already enrolled — you cannot subscribe after losing the seed.
Best practices going forward
Back up the seed, not the device
Write the 24 words on paper and on a metal backup plate (Cryptosteel, Billfodl, Stamp Seed). Store copies in two geographically separate locations (home safe + bank deposit box, for example).
Test the seed before funding
After setup, deliberately wipe the device and restore from your written seed. If it restores, you know the backup works. Only then deposit real funds.
Use SLIP-39 or multisig for large holdings
Trezor Model T and Safe 3 support SLIP-39 Shamir Secret Sharing natively. For serious amounts, a 2-of-3 multisig across different vendors (Ledger + Trezor + Coldcard) is the gold standard — survives any single device or seed loss.
Never type your seed into a computer
The seed exists on paper, metal, or inside a hardware wallet. Typing it into Notepad, a browser, or an online decryptor is how people lose their savings.
What we can and cannot help with
We can help
- • Recover forgotten BIP39 passphrase (the optional 25th-word)
- • Find missing seed words (1–3 unknowns)
- • Recover the wallet password on a software wallet file
- • Decrypt MetaMask / Electrum / Bitcoin Core wallet files
We cannot help
- • Recover a forgotten Ledger / Trezor PIN
- • Extract a seed from a working hardware wallet
- • Restore funds if both device and seed are lost
- • Crack the secure element — no one can, at consumer prices

Frequently asked questions
I forgot my Ledger PIN, can it be recovered?
No. The PIN is verified inside the secure element; after 3 wrong attempts the device wipes. Reset and restore from the 24-word recovery phrase. Without the phrase, funds are lost.
I forgot my Trezor PIN, can it be recovered?
No — 16 wrong attempts and the device wipes. Restore from the 12/18/24-word BIP39 seed. Historical voltage-glitch attacks are patched on current models.
If I lose both my device and my seed phrase, can my crypto be recovered?
No. The seed phrase is mathematically the only representation of your keys. Without it and without the unlocked device, funds are permanently inaccessible. "Blockchain forensics" claims are scams.
What about the Trezor voltage-glitch attack?
A 2019 research attack on Trezor One, requiring physical possession and specialised lab equipment. Extracted only the encrypted seed — still needed the passphrase if set. Patched on Trezor Model T / Safe line.
Is the Ledger Recover service safe?
Opt-in only. Splits seed into three shards held by three custodians, recoverable via ID verification. Controversial because it puts shards of your seed in third-party custody. Useful only if you enrolled before losing the seed.
Partial seed or forgotten passphrase?
Those we can help recover. Upload the wallet file or details, list what you remember, pay only on success.
