[Firebase] 3. Firebase Simple Login Form

Using $firebaseSimpleLogin service. 

Here we use three methods for login, logout, register and getCurrentUser.

Be sure to open the Email and Password configuration on Forge:

login.tmpl.html

<div class="container" ng-controller="LoginCtrl">
    <h2>Login From</h2>
    <form class="form-signin">
        <h3 class="for-signin-heading" ng-if="currentUser">{{currentUser.email}}</h3>
        <input ng-model="newUser.email" type="email" class="form-control" placeholder="Email address"/>
        <input type="password" placeholder="Password" ng-model="newUser.password" class="form-control" />
        <button class="btn btn-lg btn-primary btn-block" ng-click="login(newUser.email, newUser.password)">Login</button>
        <button class="btn btn-lg btn-success btn-block" ng-click="register(newUser.email, newUser.password)">Register</button>
        <button class="btn btn-lg btn-danger btn-block" ng-click="logout()">Logout</button>
    </form>
</div>
