Use a BIP39 passphrase on Jade Plus without losing access

A BIP39 passphrase can protect a Jade Plus wallet if someone finds the recovery phrase but not the separate passphrase. It can also permanently lock you out if it is lost, misspelled, or entered with different capitalization or spacing. Set one up only after the base recovery phrase has been backed up and tested.

Official reference: Add a BIP39 passphrase for Jade.

Enter it only on trusted hardware: Enter a real passphrase only in the manufacturer's documented hardware flow. Never enter a recovery phrase or passphrase into a phone, computer, website, Sparrow or another coordinator, cloud form, chat, or support ticket.

Understand what the passphrase does

The recovery phrase and passphrase are inputs to wallet creation. The same recovery phrase with no passphrase, with Example A, or with example a creates three different wallets.

A passphrase is sometimes called a “25th word,” but that label is misleading. It is not literally a 25th word, does not have to be one word, and is not part of a 24-word phrase's checksum. It can contain multiple words, spaces, numbers, or other characters supported by the device.

Every exact passphrase creates a valid wallet. Jade cannot know which one you intended. A typo normally opens an empty, different wallet instead of showing “wrong passphrase.” Read Recovery phrase vs. final word vs. passphrase before continuing if these secrets are unclear.

Decide whether the trade-off fits

A passphrase is useful when recovery-phrase theft is a realistic risk and you can keep a second secret available for recovery. Do not use one if memory is its only backup or if a successor will not know that it exists.

Choose a passphrase generated by a documented random process rather than a quotation, birthday, address, song lyric, or sentence you invented. A published Diceware-style process can generate several independent words. The effective strength also depends on the device's supported length and character handling, so test the complete value on the exact recovery hardware you plan to use.

Record the passphrase exactly, including:

• word order;
• capitalization;
• spaces, including repeated spaces if permitted;
• punctuation or other supported characters.

Store that record separately from the recovery phrase. Do not rely on memory alone.

Create the passphrase wallet on Jade Plus

Follow Blockstream's current passphrase instructions on an unfunded or small-value test wallet. Do not rely on a remembered menu path: firmware labels can change. Jade supports device-side entry methods; preserve the exact lowercase words and spaces if you use its word-list method.

Official reference: Blockstream's passphrase guide linked above. The image contains no real wallet secret.

After entering the intended passphrase:

1. Open the resulting wallet.
2. Record Jade's eight-character wallet fingerprint on a private recovery worksheet.
3. Generate a receiving address and verify the complete address on Jade.
4. Send a small amount and spend part of it.
5. Power Jade off.
6. Enter the passphrase again and confirm the same fingerprint and address.

A fingerprint is not a private key, but it is sensitive wallet metadata. It is a compact check, not a substitute for verifying a known address and completing a recovery test.

Test recovery before depositing more

Use Jade's documented Temporary Signer flow or a spare/reset test Jade. Enter the recovery phrase and passphrase only on that trusted hardware. Confirm the expected fingerprint and a previously hardware-verified address, then sign a small transaction.

Do not reset your only funded Jade to perform the test. Use spare hardware or a test wallet. Confirm that any different hardware model supports the same backup format, passphrase characters and length, script type, and derivation behaviour before treating it as a recovery path. See Test a Bitcoin wallet recovery.

Diagnose an apparently empty recovery

An empty wallet does not prove that funds disappeared. Stop before sending or changing the old setup. Check:

• passphrase spelling, case, spacing, and punctuation;
• recovery-word spelling and numbered order;
• whether the intended wallet used a passphrase at all;
• network, script/address type, derivation settings, and account;
• the expected fingerprint and known verified address.

Do not ask support to inspect either secret. Support can explain official recovery flows without seeing recovery words or a passphrase.

Add the passphrase's existence and separate location to your Bitcoin inheritance plan, but do not place it beside the recovery phrase or in an ordinary will.
