Vueプロジェクトにおけるロック画面機能追加の実装アイデアについて

 handleSetLock() {
  this.$refs['form'].validate(valid => {
  if (valid) {
   this.$store.commit('SET_LOCK_PASSWD', this.form.passwd)
   this.handleLock()
  }
  })
 },

 SET_LOCK_PASSWD: (state, lockPasswd) => {
  state.lockPasswd = lockPasswd
  setStore({
  name: 'lockPasswd',
  content: state.lockPasswd,
  type: 'session'
  })
 },

 SET_LOCK: (state, action) => {
  state.isLock = true
  setStore({
  name: 'isLock',
  content: state.isLock,
  type: 'session'
  })
 },

 if (store.getters.isLock && to.path !== lockPage) {
  next({
  path: lockPage
  })
  NProgress.done()
