      protected $fillable = ['username', 'password', 'name', 'avatar', 'google2fa_secret'];
   
      public function setGoogle2faSecretAttribute($value)
      {
         $this->attributes['google2fa_secret'] = !is_null($value) ? encrypt($value) : null;
      }
   
      public function getGoogle2faSecretAttribute($value)
