 As mentioned in [Defining accounts](#defining-accounts), an account name can be any string. Using an arbitrary string as an account name can be convenient. For example, you might want to create an account with a name that identifies it as a personal or primary account, for example, Lola-Pistola, so that it's easy to differentiate it from an account that you own jointly with another party or a group, for example, Las-Pistolas.
 
-However, using arbitrary account names like these examples can make your account vulnerable to certain kinds of attacks. For example, an attacker might try to hijack a transaction that creates an account or transfers funds by changing the guard associated with the account name. One way to prevent an account from being hijacked by an attacker is to create **principal** account. A principal is a way to enforce a one-to-one relationship between a guard and what the guard is there to protect, like the ownership of an account balance. If an attacker tries to hijack the account by changing the guard, the guard won't match the account as it's defined in the underlying ledger, so the guard would be rejected and the transaction would fail.
