    <para><ulink url="https://systemd.io/CREDENTIALS">System and Service Credentials</ulink> are data objects
    that may be passed into booted systems or system services as they are invoked. They can be acquired from
    various external sources, and propagated into the system and from there into system services. Credentials
    may optionally be encrypted with a machine-specific key and/or locked to the local TPM2 device, and are
    only decrypted when the consuming service is invoked.</para>

    <para>System credentials may be used to provision and configure various aspects of the system. Depending
    on the consuming component credentials are only used on initial invocations or are needed for all
    invocations.</para>

    <para>Credentials may be used for any kind of data, binary or text, and may carry passwords, secrets,
    certificates, cryptographic key material, identity information, configuration, and more.</para>
