}

	// GetID returns a globally unique ID for the user.
	GetID() string
	// GetDatabaseUsername returns in-database username for the user.
	GetDatabaseUsername() string
	// Setup preforms any setup necessary like creating password secret.
	Setup(ctx context.Context) error
	// Teardown performs any teardown necessary like deleting password secret.
