You cannot open a view with window.open (url).

You can use axios (or similar) to request authentication on your server.

When clicking on the login button: send the login and password with Axios to the server authentication endpoint (for example: www.yourserver / login / connect.php), in POST mode.

Your server will need to authenticate you and return a response. In the view, the answer can be tested in the callback part of the request: a method is provided for this.

If successful : access your dashboard page (window.open ("www.Yourserver / dashboard.php ").

note : the dashboard.php must verify if you are really authorized.

If you use spa logic (single page application). You will use vueroute and probably vuex.js.

I think you need to deepen the concept vue.js / spa application / landing page / vueroute.js / vuex.js / axios (or similar). good luck.
