Hello Gareth,

thank you very much for sharing.
This helps me a lot, get my authentication running, because before that I could only login, but the state was gone after reload.

I have made a little improvment for the Firebase call.
I´ve put it into the store too.
As seen in this tutorial from Max.

This in store.js:

actions: {
  setUser: context => {
    context.commit('setUser')
  },
  signUserIn ({ commit }, payload) {
    Firebase.auth()
      .signInWithEmailAndPassword(payload.email, payload.password)
      .then(newUser => {
        commit('setUser', newUser)
      })
      .catch(error => {
        console.log(error.message)
      })
  }

and in signup.vue I call it this way

onSignin () {
  this.$store.dispatch('signUserIn', { email: this.newUser.email, password: this.newUser.password })
}
