Recovery Phrase Entropy Check
Recovery phrase entropy verification & xPub export
ONLINE TOOL
You are using the official online verification tool. For maximum security, all recovery data is generated locally on your device, while validation and integrity checks are performed through official servers.

BIP-39 uses the 2048-word English list (e.g. abandon, about). Ensure you enter all words in the correct order.

Phrase entropy —
Low entropy detected The word distribution in your recovery phrase suggests lower-than-expected randomness. Shift Crypto recommends generating a new seed on your BitBox02 if this was not intentionally created. You may continue to verify and export your xPub for offline authentication.

Not part of your recovery words. BitBox uses the same optional passphrase with BIP-39 and SLIP-39 — a different passphrase unlocks a different hidden wallet.

Analyzing phrase entropy…
Validating word list (BIP-39 or SLIP-39)…

Enter a single private key (WIF, Hex, or Ethereum format) to verify entropy and prepare for offline signing.

Security Warning: Private keys grant full access to your funds. Only use this tool on a trusted, offline device.
Verifying Private Key…
Validating format and checksum…

Paste an existing extended public key to verify format and prepare it for BitBox App offline authentication.

Never share your recovery phrase. Extended public keys are safe for watch-only verification.
