# Externally Owned Account (EOA)

An Externally Owned Account is an address where control of the address sits entirely with a private key stored off-chain. Think of the private key as a password -- and whoever has the password controls the account. 

The canonical example of such an address is an Ethereum address that is not a smart contract, it is just an address secured by a private key held by some person.
