Firebase 3.x - Token / Session Expiration

Question

Does anyone know how long would it take for the token to expire? There no option now to set the token validity on the console.

Answer 1

If the above answer is still confusing to you, This is what i did:

firebase.auth().onAuthStateChanged(async user => {
    if (user) {
        const lastSignInTime = new Date(user.metadata.lastSignInTime);
        const lastSignInTimeTimeStamp = Math.round(lastSignInTime.getTime() / 1000);
        const yesterdayTimeStamp = Math.round(new Date().getTime() / 1000) - (24 * 3600);
        if(lastSignInTimeTimeStamp < yesterdayTimeStamp){
          await firebase.auth().signOut()
          this.setState({
            loggedIn: false
          });
          return false;
        }
        this.setState({
          loggedIn: true,
          user
        });
      }
    })
