Where is the best place to store a user token in VueJS?

I'm building a VueJS client application where after the user logsin, the API is return a token. I'm using Vuex, but as far as I understand the response is stored in state in memory only. In almost every example I see data like a token is written to localStorage which creates a security risk. What is the best way to persist the token after login (not localStorage nor cookies)? example are appreciated
