# DeleteAlias
Deletes the alias, but doesn't affect the underlying key.
Each key can have multiple aliases. To get the aliases of all keys, use the [UpdateAlias](https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_UpdateAlias.html) operation. To change the alias of a key, first use [DeleteAlias](https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_DeleteAlias.html) to delete the current alias and then use [CreateAlias](https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_CreateAlias.html) to create a new alias. To associate an existing alias with a different key, call [UpdateAlias](https://docs.aws.amazon.com/payment-cryptography/latest/APIReference/API_UpdateAlias.html).
**Cross-account use:** This operation can't be used across different AWS accounts.
