Anyone with the private key controls the funds, so it must be kept secret and backed up safely. Lose it and the funds are usually unrecoverable; expose it and they can be stolen.
Puntos clave
- A private key is the secret value that proves ownership and authorises spending from a crypto address.
- Anyone who obtains your private key can move your funds, so it must never be shared.
- Private keys cannot be reset or recovered by a provider if lost, unlike a normal password.
