Private-Key

Private-Key: 
Defined in Cryptocurrency

A Private-Key is a randomly generated secret number that must only be known to the owner of the associated address, and no-one else.

Private-keys are contained in a wallet and are mathematically linked to the corresponding public-keys.

A Private-Key can be used to spend the funds that are associated with a specific address and should always be kept private.

Publicly sharing a Private-Key will result in a loss of funds; -i.e. most likely theft.


Private-Key are generated locally on your Trezor-device and never leave the device.

The Private-Key is defined as a string of letters and numbers known only by the owner that is used to spend cryptocurrency.

NEVER SHARE your Private-Key with anyone unless you want someone else to be able to theft, and-or own all of your money!


Your Private-Key is your most prized possession as your password is to access your cryptocurrency account(s) and must always be in private.

Compare a Private-Key with a Public-Key and address:
Your Public-Key is rarely ever used, but you can use it to receive cryptocurrency in trust.

Your address is a safer version of your Public-Key and is what you should use to receive money.

Private-Key for Trezor devices are generated based on a recovery-seed and (optional) passphrase.

In addition to creating and signing transactions, Private-Key can be used in the Trezor-Wallet to sign messages from a specific address to prove ownership of that address.
