Safe 3 is a hardware wallet for storing cryptocurrencies. It is the third generation of Trezor hardware wallets. The Trezor Safe 3 was unveiled at the Bitcoin Amsterdam conference held on August 3, 2023 in Amsterdam. Trezor Safe 3 features an embedded Secure Element chip that provides an extra layer of security for your private data.
Key features of Trezor Safe 3 include:

• 2FA and FIDO2 support
• Coinjoin support
• Support for Shamir's split recovery seed
• Protection against physical attacks

Although it is a new device, the similarity with its predecessor Trezor One is noticeable. And no wonder. As they say - simplicity is power. New to Trezor Safe 3 is USB Type-C.
Trezor Safe 3 is aimed at a wide range of users looking for a reliable and secure hardware wallet to store their cryptocurrencies. It is the perfect choice for users who are just getting acquainted with cryptocurrencies, it also offers a wide range of features and options that will satisfy even the most demanding users.

The whole process of setting up a new device is quite simple and you will be guided through the steps by the device itself with the downloaded program.

Once installed, the software automatically detects the device and guides you through the installation steps. The first step is to check and update the firmware on the device.

After installing the firmware, we can choose whether we want to create a new wallet or restore an existing one. When creating a wallet, we can choose a classic backup in the form of a list of 12 English words - the so-called Recovery seed. We can also choose a more advanced method - Shamir backup. I chose the classic backup for illustration.

Words are displayed in groups of three. The list can be initially written on the paper included in the package. It is definitely not recommended to take any photos, save them to a PC or otherwise digitally record them.

After setting up your wallet, all that's left to do is set up the PIN for the device itself. The minimum length of the numeric password is four characters. The maximum is fifty characters.

The device setup is almost complete. Next is the option to select cryptocurrencies. I had already selected BTC only during the initial firmware installation, so I only have BTC available.
We can then choose which wallet we want to log into. Whether to the classic , or hidden.
The hidden wallet in Trezor Safe 3 is another wallet that is located on the same device as your main wallet. This wallet is hidden from normal use and can only be accessed by entering a special "passphrase". Basically, this passphrase (password) is like another word for seed. There can be multiple hidden wallets with different passphrases. However, without this passphrase you will not be able to access your hidden wallet.

The "tutorial" described above was about creating a new wallet. But what if we want to restore the wallet? Again, the process is simple.

Unlike creating a new wallet, which offers a 12-word list to restore a wallet, we can restore a wallet from a 12- , 18- , 20-, 24-, or 33-word list.

Use the arrow keys to form a word, which is then confirmed by pressing both buttons.

This is how we put together all the necessary words from the list. I used a list of 24 words for the recovery. After restoring, the procedure is similar to that for securing a new wallet. Namely, setting the PIN etc. .

I have tried setting up and restoring my wallet on the device several times and have not encountered any tricky issues. However, the challenge for me remains Shamir backup and here unfortunately I cannot provide any experience of my own.
Overall, the device appears very favorable and robust. The controls are simple, the buttons respond as expected. The buttons need enough pressure to "react" , but at the same time they are not too stiff.
Simply, the Trezor team seems to have done a good job.

What about my Trezor One? That's being recycled by my son. He's already set up his wallet there :-D
