Imagine you own a wallet that is inside of a locker and has $20 in it, the locker key is a security measure because you need it to open the locker and get the wallet. Bitcoin uses a similar system in order to secure your wallet by proving users with a private key or seed. This key is an authorization method that allows the buyer to use bitcoins from a specific wallet.
