Can anybody explain what is the difference between these 2 methods in Ember Simple Auth:

```auto
routeAfterAuthentication

and

routeIfAlreadyAuthenticated

```

I have 2 apps that have these two parameters defined in `environment.js` and I’d like to know when to use one or another. Thank you.

They are two different things:

- `routeAfterAuthentication` is where to transition after a successful login.
- `routeIfAlreadyAuthenticated` is where to go if the user is already authenticated and visits a page which makes no sense to visit if you’re logged in (`login`, `register`, a guest homepage, etc.)

Hi Balint! Thank you for your response. So following your book, where we have it defined as follows in `environment.js`:

```auto
# environment.js
module.exports = function(environment) {
  let ENV = {
...
 'ember-simple-auth': {
      routeIfAlreadyAuthenticated: 'bands'
    },
...

```

it seems like there is no difference in which one to use, both will make the transition to `bands` route. Right ?

The two config variables have different meanings but in some cases they might overlap, like in the Rock and Roll app. The important thing is to see how they differ.
