Private Key
A secret cryptographic code that gives you control over your cryptocurrency.
Explained Simply
A private key is a long string of numbers and letters that acts as the password to your crypto. Anyone who has your private key can spend your funds. This is why you should never share it and never enter it into websites. Most wallets manage private keys behind the scenes — you interact with a seed phrase (recovery phrase) instead. Hardware wallets store private keys on a dedicated device that never connects to the internet.
