### Method

# EDataServerUI4 CredentialsPrompterregister_impl

since: 3.16

#### Declaration [src]

    gboolean
    e_credentials_prompter_register_impl (
      ECredentialsPrompter* prompter,
      const gchar* authentication_method,
      ECredentialsPrompterImpl* prompter_impl
    )

#### Description [src]

Registers a prompter implementation for a given authentication method. If there is registered a prompter for the same `authentication_method`, then the function does nothing, otherwise it adds its own reference on the `prompter_impl`, and uses it for that authentication method. One `prompter_impl` can be registered for multiple authentication methods.

A special value `NULL` can be used for the `authentication_method`, which means a default credentials prompter, that is to be used when there is no prompter registered for the exact authentication method.

Available since: 3.16
