Upgrade your security

Unleash Passphrase

Create as many hidden wallets as you want on your ZERO. The Coldest Wallet got even colder.

What is passphrase?

This security feature extends your Perfect Key or seed phrase. Adding a passphrase creates a new hidden wallet with new coins and addresses. They are not stored on ZERO, and you can create as many as you want.


Create the coldest passphrase

In 'Settings' > 'Passphrase', create your own sequence between 1 and 512 characters. They are case-sensitive and spaces count. 


Unlimited hidden wallets

A green icon on the top left of your dashboard indicates you are in a Passphrase Wallet. Here you can add coins and accounts, like in your Main Wallet.


Easy access to your wallets

If you have Passphrase wallets or more than one ZERO, sync them all to your LIQUID. You can name your wallets, assign avatars, and transfer funds between them with ease.


Update your ZERO

Enjoy the Passphrase feature in your favorite crypto wallet.

  • Will I need to create a new wallet or private key to use a passphrase?

    No, you can keep your current wallet. There is no need to wipe it to use the passphrase feature. Each passphrase you add will create a new wallet and set of addresses. Sync multiple wallets with the LIQUID app to easily transact between them.

  • What are the requirements of a passphrase on ZERO?

    The passphrase on ZERO aims to be compatible with other wallets. For interoperability you'll also need to consider the specifications of other wallets.

    A valid passphrase on ZERO is between 1 and 512 characters long. All ASCII printable characters are allowed except ` , the Grave accent.  A space is also a valid character.

    So, a passphrase is case-sensitive and can be made up of separated words.

  • How should I store my passphrase(s)?

    There isn't a singular 'best' method to store your passphrase, but as a general rule you should keep it as secure as your Perfect Key or seed phrase. Just like your backup, it should be stored offline and kept private.

    Memorizing your passphrase offers the advantage of being virtually impossible to find. However, the obvious risk is the potential of forgetting it. If your passphrase is complex or rarely used, engraving it onto metal could be a more reliable option.

    If you make a physical backup of your passphrase, don’t store it together with the backup of your Perfect Key or 24 word seed. Treat it as 2-factor authentication to protect your funds in case the backup of your Perfect Key or seed phrase gets compromised.

    It is your own responsibility to store it securely. If you lose your passphrase, you lose access to that wallet.

  • Can a passphrase act as a ‘duress PIN’?

    No. You can set up a passphrase wallet with a small amount of funds that can act as a duress wallet. But this is something different than a separate PIN code that wipes your wallet when you enter it.
