KAS uses Basic HTTP Auth. All requests must contain a valid Authorization header. KAS users must use access key ID as username, and secret access key as password to create credentials for Basic Auth. The KAS account credentials grant access to all services of KAS and own all rights to the Kaia account created by Wallet API, which means they can execute value transfer of assets on the Kaia account (such as KAIA) or a Transaction execution. To keep your KAS/Kaia account secure, do not share your KAS API Secret Access Key with others and manage it safely.
