Synonyms: recovery sentence, recovery phrase, mnemonic.

The recovery seed is used for a ONE-TIME backup. That means that if lost, your cryptocurrency is gone unless you can successfully hack your own HD, as Kraken Labs have. The recovery seed must be stored in a safe location, such as a sealed envelope in a physical safe or safety deposit box.

Recovery seeds are a string of English words that, when entered correctly, will recover all of the information stored on the HD wallet. Trezor One generates a 24-word seed during the initialization process when the owner “creates a new wallet.”

Trezor recovery seed consists of a set of English words (24 for the Trezor One). From these words, all account private keys, all private keys, public keys, and addresses are mathematically derived.

To create the recovery within the Trezor devise, a 256-bit random number is generated on its Microcontroller with a Random Number Generator. Then, a random number of the same length is generated by the connected computer and then sent to the Trezor device. These two numbers (the 256-bit and computer-generated number) are then hashed with the SHA-256 algorithm.

And, behold, you have your unique recovery seed.

The setup process is very straightforward, and there are many tutorials and explanations available online, as well as on here, on the Trezor FAQ site.

1. Plug the Trezor USB into your computer’s USB port. Your screen will display an image of a lock and the link you need to follow.
2. Follow the link to the webpage. Once you have read the instructions on how to keep your wallet safe, you will be redirected to wallet.TREZOR.io.
3. Once you install your Trezor wallet, it will be able to communicate with the blockchain. You can a) install a Google Chrome extension, or b) download the blockchain onto your Trezor.
4. Follow the instructions to install the latest firmware and click “Yes, Install”. (Firmware provides the control program for the device.)
5. Afterwards, you must check that the Fingerprints on your Trezor hardware screen match those displayed on your computer’s device screen. If it does match, on the Trezor wallet, click “Continue.”

Fingerprint example:

For firmware 2.1.0:

trezorctl firmware-update –fingerprint bb5b0308807b45d41d1e2ab66a468152997ad69a01099789d8a35e464cde999f

6. Next, unplug the wallet from the USB, then re-inert it, and return to wallet.TREZOR.io.
7. 7. Name your Trezor wallet (which can be changed at any time).
8. Choose your PIN. You will see an image similar to the following one on the Trezor devise.

Unlike a PIN entered on a computer or mobile, your Trezor PIN cannot be compromised by malware. The numbers are in a random order to ensure that an attacker is not able to view your selection. 1) enter the PIN on your computer, twice. 2) You must select the same position on the pin-pad.

9. Once your PIN is set, the wallet will display your 24-word backup recovery seed.

In the event of a lost PIN, you will need your recovery seed to set a new PIN. But if you lose your recovery seed there is very little that can be done. Although it is worth contacting SatoshiLabs to hear what they have to say.

Users can use their Trezor wallet to make transactions. To send funds, you must plug the wallet into your computer and enter your PIN. You must do so each time you wish to make a transaction directly from your wallet. This may seem like a cumbersome process to some users.

Transfer Cryptocurrency To your Trezor Wallet: How To

1. Plug your Trezor hardware wallet into a USB port of your computer and enter your PIN.
2. Using the Google Chrome extension or another software program, you will be taken to your Trezor wallet.
3. On the top-left side of the page, there is a drop-down box. Choose the cryptocurrency that you want to send to your Trezor wallet.
4. Click “Receive” at the top of the screen. You will then see your unique wallet address for the cryptocurrency you want to transfer/a QR code.
5. Copy the address and paste it into your Trezor wallet and your cryptocurrency will be moved into cold-storage.

Note: The amount of time it takes to complete the transfer of your cryptocurrency into your Trezor will depend on the coin.

Send Funds from your Trezor Wallet: How To

1. Open the Trezor wallet dashboard on your computer.
2. Select the coin you would like to send from the drop-down menu.
3. Select “Send” at the top of the page.
4. Enter the wallet address of whomever you wish to send the money to, along with the amount.

5. Confirm that the information you have selected is correct and click “Send.”

Trezor suggests that it is best to have two separate devices: one for a password manager account authenticator, and the other to hold your cryptocurrency. This is to avoid connecting the Trezor that holds your cryptocurrency unnecessarily to a device.

Trezor works will Apple Pay as well. That means that you can use your BTC to buy items directly with Apple Pay. Your hardware wallet works to send coins directly from it to the recipient (via Apple Pay).

However, you will be subject to Apple Pay’s exchange rate, which may not be as when sold directly on an exchange.

Trezor uses an enforced delay for every failed PIN attempt. This is to prevent brute-force attacks (guessing random numbers). The delay increases by a factor of two for each failed entry.

16 incorrect PIN attempts and the device will wipe itself. At this point, you must use your recovery seed to reset your PIN. If you need to use the recovery seed the Trezor will instruct you to enter the words in the phrase in a shuffled order. It is also best to enter the recovery seed directly into the wallet, this way it is never on your computer’s keychains.

You can also add a passphrase as an optional second-factor function with the recovery seed. Passphrases allow users to create hidden wallets.

Lastly, Trezor/SatoshiLabs representatives will never ask for your recovery seed or, for a credit card number.

Trezor boxes are packages with a tamper-evident hologram or holographic seal. This way, if your box arrives and the hologram is not intact, you can quickly detect if it has been tampered with.

The TREZOR One package has two silver seals on both sides. It is designed so that it is impossible to open without destroying the box in the process. To first open the box, the hologram will be destroyed.

If your box arrives and looks as though it has been tampered with, then you must contact the Support Team at Trezor.

On January 31, 2019, Kraken Security released a statement that their research team was able to hack the Trezor hardware wallet. The hack takes less than 15 minutes and is the result of a vulnerability.

Kraken reports that the vulnerability is in KeepKey. Kraken Security Labs states that the vulnerability lies in the microcontroller of the Trezor wallets. So, to remedy the solution requires a complete overhaul of the cold storage device’s design.

While Trezor is aware of this weakness they have not made any changes.

Here is how Kraken Security Labs was able to hack the hardware wallet.

Trezor Support Will:

• Troubleshoot any problems with Trezor hardware wallets and SatoshiLabs software.
• Suggests that contacting SatoshiLabs directly will yield much faster results than social media.
• Once you receive an email confirmation from customer support, your ticket is in the queue.
• You will receive regular updates on the status of your ticket until you are connected to the support staff.
• Remember to check your junk folder if you do not hear back in a reasonable timeframe when first launching your concern.

Trezor is a reasonably priced hardware wallet that will go a long way to keeping your cryptocurrency secure. It has its limitations, but many of the problems are user errors, such as: lost recovery seeds, lost devices, etc.

While it touts over 1600 cryptocurrencies, that does not cover all cryptocurrencies; the Trezor T Model, the latest model supports more digital coins. And, many of these currencies are ERC-20 tokens for Ethereum.

Trezor wallets are not just for cryptocurrency. The applicability of asymmetric keys can be used to sign and verify any kind of data. Which means that Trezor wallets work to store and encrypt passwords for any of your private digital information.
