What is a passphrase?

This article explains how passphrases work with Trezor devices.

The passphrase is an optional advanced feature that lets experienced users create additional wallets that require a custom passphrase to access.

A passphrase creates a completely new wallet that is linked to your existing wallet backup, also known as a recovery seed (12, 18, or 24 words).

Think of the passphrase as an extra word or phrase you add to unlock a different wallet. It adds another layer on top of your wallet backup.

Every passphrase you enter creates a different wallet, even if it’s a typo or mistake.
Passphrase wallets are separate from your standard wallet, and you can only access them by entering the exact same passphrase used before.

Passphrases cannot be changed, removed, or recovered.

If you lose your passphrase, you lose access to your passphrase wallet and its funds.

Always write down your passphrase, store it securely, and test your access regularly.

After connecting and unlocking your Trezor device, open the wallet menu in the top left corner of Trezor Suite and select + Passphrase wallet to enter a custom passphrase and access the corresponding wallet.
You’ll be prompted to enter a passphrase—either on your device (Trezor Safe 5, Trezor Safe 3, or Trezor Model T), or in Trezor Suite (all models).
The passphrase is case-sensitive and can be up to 50 ASCII characters long.
Your Trezor combines your wallet backup and the passphrase to generate a unique wallet.
If the passphrase matches one you've used before, you'll access that same passphrase wallet.
If it’s a new or mistyped passphrase, a different wallet will open—most likely empty. This doesn’t mean your funds are lost. It just means the passphrase doesn’t match the one used originally.

Reminder: Your Trezor device doesn’t store your passphrase. You’ll need to enter it manually every time you want to access the associated wallet.

Using a passphrase wallet requires both:

If either is missing or incorrect, the wallet cannot be accessed.

Entering a different passphrase—intentionally or by mistake—creates a new, empty wallet.

Write down your passphrase and store it securely.
Regularly test your access by accessing your wallet and entering your passphrase.
Consider your needs before using this feature. It is optional and advanced, and not recommended unless you fully understand the risks.
