Code:
  constructor(options: AuthenticatorOptions = {}) {
    this.key = options.key || 'passport'
    this.userProperty = options.userProperty || 'user'

    this.use(new SessionStrategy(this.deserializeUser.bind(this)))
    this.sessionManager = new SecureSessionManager({ key: this.key }, this.serializeUser.bind(this))
  }
