Using PIN with Trezor [edit]

Entering PIN [edit]

Trezor employs an original method of entering PIN. Trezor One uses a blind matrix (see this video). Trezor Model T uses its own touchscreen. Entering the PIN like this is both convenient and highly secure. Therefore, unlike a PIN entered on a PC or a smartphone, a PIN entered on Trezor devices cannot be compromised by malware. For more information, see User manual:Entering PIN.

To prevent brute-force attacks, after every failed attempt, Trezor enforces a delay before it lets you try a different PIN again. This delay increases by the factor of two each time. Moreover,

ImportantAfter 16 incorrect attempts, your device wipes itself, making it possible to access your funds only with the use of your recovery seed.

Setting up PIN [edit]

The PIN is set during the device setup. The PIN can be up to 50 digits long and it is recommended to have a PIN that is four or more digits long without repetitions.

Changing PIN [edit]

The PIN can be changed in the basic settings of Trezor Wallet, for more information see User manual:Basic settings.

Resetting lost or forgotten PIN [edit]

In case you have lost or forgotten your PIN, your only option is to wipe your device (see Wiping the memory of a locked, PIN-protected device) and recover it with your recovery seed. Once the recovery is complete, you can set a new PIN. In case you lost your recovery seed (see User manual:Recovery), there is not much you can do (see Emergency situations).
