Why verify your Seed Phrase?

A Seed Phrase (Recovery Seed) is a set of 12 or 24 words created when you first set up your Trezor. It acts as the "Master Key" to your entire wallet. If your device is lost or damaged, this Seed Phrase can be used to recover all your assets.

The Check Backup feature allows you to confirm that the Seed Phrase you wrote down matches the one stored in your Hardware Wallet. The entire process occurs only on the device and is not connected to the internet, so you can rest assured that your Hardware Wallet is secure.

⚠️ Security Warning

Perform the verification in a private place. Do not let others see your screen or Seed Phrase.
Never type your Seed Phrase into any internet-connected device.
Download Trezor Suite only from trezor.io.

What you need

Trezor Hardware Wallet — Model T, Model One, Safe 3, or Safe 5
Recovery Seed Card — The paper or device where your Seed Phrase was recorded during initial setup.
Trezor Suite — The latest version of the Desktop application.
Trezor PIN — Used to unlock the device before starting.

Verification Steps

Step 1 — Open Trezor Suite and connect your device

Open the Trezor Suite app on your computer, then plug your Trezor into the USB port. Ensure that Suite detects the device and displays the main Wallet screen.

Step 2 — Go to the Device Settings menu

Click on the device name or device icon in the top left corner, select Settings, then scroll down to the Backup section and click the Check backup button.

Path: Trezor Suite → Settings → Device → Wallet Backup → Check

Step 3 — Read the warning and confirm to start

Trezor Suite will display a warning that this process will prompt for Seed Phrase words on the device. The Trezor screen will show "I Understand this is a simulated check. It won’t affect my Trezor or funds." Check the box next to the message, then click Start and confirm on the device to proceed.

Step 4 — Select the number of Seed Phrase words to verify

The Trezor screen will display the number of Seed Phrase words you want to verify, ranging from 12, 18, 24 words, or 20-word SLIP-39 Seed Phrases. Choose the correct number of words based on your own Seed Phrase.

Step 5 — Enter your PIN to unlock

The Trezor screen will display a keypad for entering your PIN, with the number positions randomized each time. Press the buttons according to the positions shown on the device.

Step 6 — Enter the Seed Phrase words as prompted by the device

Trezor will display the word number, such as "Word #1", on the screen, and you will click the letters of that word via Trezor Suite on your computer. You will enter the first letter of the word you recorded, one letter at a time on the computer screen. The system will then auto-complete possible words. Select the matching word from the list until all words are entered.

For example, if the word you recorded is "sunset", press the keypad on your computer screen at the positions with the abbreviation "SU" as shown in the image below.

Step 7 — View verification results

Once all words are entered, Trezor Suite will display the results.

✅ Backup is valid — The recorded Seed Phrase is correct and complete, and can be used to recover the wallet.
❌ Backup is invalid / Mismatch — The entered words do not match the Seed on the device. Please recheck your recorded words.

If the result is Invalid: Do not transfer any more assets to this wallet. Check if your Seed Card is correct. If not, transfer all assets to an exchange first. It is crucial to transfer all assets out of this Private Key, as you will not be able to recover them if the recorded Seed Phrase does not match the one stored on the device.

Pre/Post Verification Checklist

Do it in private — no cameras or others seeing the screen and Seed Card.
Download Trezor Suite only from the official source: trezor.io.
Ensure your Firmware is the latest version before verification.
Your Seed Phrase should be recorded, in good condition, clearly legible, and not faded.
Never take photos or type your Seed Phrase digitally under any circumstances.
Verify regularly every 6–12 months.

Additional Tips

Store your Seed securely — Use a fireproof and waterproof safe or a metal backup plate instead of paper.
Verify regularly — Perform a Check Backup every 6–12 months to ensure your Seed Card is still readable and correct.
Passphrase Wallet — If you have set a Passphrase, your original Seed Phrase is still correct, but the wallet displayed will differ depending on the Passphrase used.
Backup in multiple locations — Keep copies of your Seed in several secure locations to protect against emergencies like fire or flood.
