How to load another layout(Vue)?

Question

Vue.js

Faced this problem: There are two layouts, one for the login/registration pages, the other for everything else.

<template>
  <v-container>
    <Default v-if="..."/>
    <Auth v-else/>
  </v-container>
</template>

What condition should be set so that when switching to auth/login (vue-router) another layout is loaded.
ps Tried through the store and watch property, it does not work, and in the second case it also gives an error.
