# Get the logged in user

At any time, you can use the `currentUser` property to get the signed in user.

```javascript
const currentUser = adamite().auth().currentUser;
const userId = currentUser.id;
```

You can also subscribe to changes to the auth state using the `onAuthStateChange` method.

```javascript
adamite().auth().onAuthStateChange(currentUser => {
  if (currentUser) {
    console.log("logged in as " + currentUser.id);
  } else {
    console.log("not logged in");
  }
});
```

The `onAuthStateChange` method returns a function that can be called to unsubscribe from auth state changes.

```javascript
const unsubscribe = adamite().auth().onAuthStateChange(currentUser => {
  // ...
});

unsubscribe();
```
