/**
 * SECTION:secret-password
 * @title: Password storage
 * @short_description: Simple password storage and lookup
 *
 * This is a simple API for storing passwords and retrieving passwords in the
 * Secret Service.
 *
 * Each password is associated with a set of attributes. Attribute values can
 * be either strings, integers or booleans.
 *
 * The names and types of allowed attributes for a given password are defined
 * with a schema. Certain schemas are predefined. Additional schemas can be
 * defined via the %SecretSchema structure.
 *
 * Each of the functions accept a variable list of attributes names and their
 * values. Include a %NULL to terminate the list of attributes.
 *
 * Stability: Stable
