Password, seed phrase, PIN or passphrase — what did you actually lose?
These four terms get mixed up constantly, and each one is a completely different problem with a completely different recovery path. Knowing exactly which one you face is the difference between days and weeks — or between possible and impossible.

“Password” and “seed phrase” are two different doors. If you still have the seed phrase (usually 12–24 words for BIP39 wallets — some families differ, such as Monero 25-word seeds or Polyseed 16-word seeds), the forgotten wallet password usually stops mattering — restore the wallet with the phrase and move on. If the seed is gone too, the password is the key, and your path depends on the wallet format and what you remember.
The words people use casually — “password”, “phrase”, “PIN”, “code”, “key” — hide several very different doors. Before you try anything, find out which door is locked. A wallet password and a seed phrase are different credentials: a seed phrase may restore a wallet without the old wallet password, depending on the wallet.
The credentials, side by side
| What you lost | What it is | What happens without it | Recovery path |
|---|---|---|---|
| Wallet password | Unlocks an encrypted wallet file — e.g. wallet.dat, an Electrum wallet, an Ethereum keystore JSON |
You can’t open the file — but your keys still exist inside it | Search, recall, or targeted password recovery on the file |
| Seed phrase (recovery phrase) | Usually 12–24 words for BIP39 wallets, but some wallet families use different lengths — such as Monero 25-word seeds or Polyseed 16-word seeds. In seed-derived wallets the phrase derives the wallet’s normal accounts; manually imported private keys, JSON accounts, hardware-wallet accounts or accounts from another phrase may need separate recovery material | Without it, the wallet’s normal seed-derived accounts cannot be recreated on a new device; imported accounts need their own recovery material, and if the phrase is the only surviving material, access may be unrecoverable | Finding a copy — reconstructing lost seed words isn’t covered on this site (the search checklist) |
| Extra passphrase (“25th word”) | An optional extra passphrase / string — often nicknamed “25th word”, but not limited to BIP39 words — layered on the seed that creates a hidden wallet | The seed alone opens a different, empty wallet | Recall / structured guessing — almost always human-chosen |
| Hardware-wallet PIN / phone passcode | Local device lock — never leaves the device | The device locks or wipes itself; the keys still live in the seed | Usually not a wallet-password cracking case; restore from the seed or use device/account recovery |
| Wallet-app spending PIN | App-level PIN used by some old wallets (e.g. Bitcoin Wallet for Android/BlackBerry) | Without it, spending stays locked in that app | May be recoverable for supported wallet formats — btcrecover searches spending PINs as a numeric range |
| Exchange / custodial password | Login credentials for an account at Coinbase, Binance, Kraken or similar — the provider holds the keys, not you | The account stays locked until you regain access | Account reset through the provider, with identity verification — not password cracking |
| Private key | A single cryptographic key (WIF 5…/K…/L… or raw hex) that directly controls a balance |
Without it, that specific balance is unreachable | Only from a copy or backup — a plain private key is not guessed like a password |
| BIP38-encrypted private key | A passphrase-protected private key in a 6P… string — everything needed to rebuild the key except the passphrase |
Without the passphrase, the key stays locked | Recoverable by testing candidate passphrases offline against the 6P… string (btcrecover) — see the BIP38 guide |
| Computer / device password | The login password for the computer, phone or encrypted storage that contains the wallet | The device stays locked — and on phones and encrypted devices, recovery may require erasing the device, which can destroy local wallet data | Normal account recovery for the device — separate from wallet-password recovery, but do not reset, wipe, factory-reset or reinstall before checking whether wallet data, backups or app storage can be preserved |
The good news, first
If you still have the correct wallet file, recovery may still be possible — the file gives recovery tools something to test against. But the real odds depend on the wallet format, the file’s condition, the password’s strength and what you remember.
Mixing these up wastes weeks
People hunt for a “password” when what they lost is a passphrase, or buy new hardware when what they need is the seed. If you are not sure what you have, check the file extension and the wallet name — .dat, keystore JSON (UTC--*.json), or an Electrum wallet file in the Electrum data folder (no fixed extension — often default_wallet) — and write it down.
How to tell which one you lost
- Do you open a wallet file with a password? → You lost a wallet password.
- Do you see a recovery phrase — a grid of words? → You lost a seed phrase. Identify the wallet family first before judging it by word count: BIP39 seeds are usually 12–24 words, but Monero (25-word legacy / 16-word Polyseed) and other families differ.
- Did your wallet ask for an “extra passphrase” / “25th word” at setup? → You may have a BIP39 passphrase — a free string, not a word from the BIP39 list.
- Is it a hardware wallet asking for a short code? → That’s a device PIN.
- Do you log into an exchange website or app? → That’s an account password, and the provider may be able to reset it.
- Are you looking at a single long string that starts with
5,KorL? → That’s a private key, not a password — keep it offline and never share it. - Can you not get into the computer or phone itself? → That’s a device password — recover the device through its normal account flow, but be careful: on phones and encrypted devices a forgotten passcode may require erasing the device, which can destroy local wallet data. Do not reset, wipe, factory-reset or reinstall before checking whether wallet data, backups or app storage can be preserved.
A seed phrase is not just another password
Never type a seed phrase into this website, a form, an email, or any unknown tool — a seed phrase can recreate the wallet’s normal seed-derived accounts on any device, so anyone who receives it can move the funds. Legitimate wallet-file password recovery does not need your seed phrase; it works on a copy of the encrypted wallet file. Seed-passphrase recovery is different: if you are testing a forgotten BIP39/SLIP39 extra passphrase, the seed/mnemonic or required shares may be needed locally in an offline tool — never enter them into a website, form, email, chat or unknown tool. Wallets like MetaMask make the file case concrete: the app password only guards a local vault, and the phrase restores its SRP-derived accounts — imported private-key/JSON or hardware accounts need their own recovery material.
What to store
Whatever you lost, these five things take ten minutes and can save everything:
- Copy the wallet file — read-only — to a USB stick and a second device. Keep the originals untouched.
- Write down what you remember about the password: length, characters, words, dates, patterns. Memory evaporates fast under stress.
- Note the wallet type and version: the app name, file extension, and when you installed it.
- Note the wallet address that holds the funds, and roughly when you last used it.
- Export your password manager or check its recent items — before you forget which one you used.
If your seed phrase is intact, a forgotten PIN is usually easy to bypass by restoring on a new device. A forgotten extra passphrase is different: the seed alone may open a different wallet, so the passphrase still has to be remembered or reconstructed. If the file is intact but the password is gone, read the next guides: where old passwords hide, and how your memory built this one.
