### Interface

# Secret Backend

since: 0.19.0

#### Description [src]

    interface Secret.Backend : Gio.AsyncInitable

`SecretBackend` represents a backend implementation of password storage.

Stability: Stable

Available since: 0.19.0

#### Prerequisite

In order to implement Backend, your type must inherit from`GAsyncInitable`.

#### Implementations

- SecretService

#### Functions

###### secret_backend_get

Get a `SecretBackend` instance.

since: 0.19.0

###### secret_backend_get_finish

Complete an asynchronous operation to get a `SecretBackend`.

since: 0.19.0

#### Properties

###### Secret.Backend:flags

A set of flags describing which parts of the secret backend have been initialized.

since: 0.19.0
