Firebase Simple Login is a simple, easy-to-use authentication service built on top of Firebase Custom Login, allowing you to authenticate users without any server code.

Enable authentication via a number of third-party providers, anonymous login, or email / password authentication without having to manually store authentication credentials or run a server.

Firebase Simple Login for iOS is now a part of the core Firebase iOS library. As a result, this standalone Simple Login client is being deprecated. We encourage everyone to upgrade to the latest version of the Firebase iOS Client to get the latest and greatest features. If you are still using this deprecated Simple Login client, you can find documentation for it here.

You can read more about this change on our blog and see the updated login documentation on our website. The updated documentation includes migration plans, but if you have any other questions, please reach out to us.

To get started with the iOS SDK, see the Firebase iOS Quickstart Guide.

To install in your application, download from the Firebase CDN.

In order to use Simple Login in a Swift project, you'll also need to setup a bridging header in addition to adding required frameworks to your project. To do that, follow these instructions, and then add the following line to your bridging header:

#import <FirebaseSimpleLogin/FirebaseSimpleLogin.h>

The Firebase Simple Login iOS Client supports email & password, Facebook, Google, Twitter, and anonymous authentication methods. Before adding to your application, you'll need to first enable these auth. providers in your app.

To get started, visit the Simple Login tab in Firebase Forge, at https://<YOUR-FIREBASE>.firebaseio.com. There you may enable / disable auth. providers, setup OAuth credentials, and configure valid OAuth request origins.

Start monitoring user authentication state in your application by instantiating the Firebase Simple Login client with a Firebase reference, and callback.

Firebase* ref = [[Firebase alloc] initWithUrl:@"https://SampleChat.firebaseIO-demo.com"];
FirebaseSimpleLogin* authClient = [[FirebaseSimpleLogin alloc] initWithRef:ref];

let ref = Firebase(url:"https://SampleChat.firebaseIO-demo.com")
var authClient = FirebaseSimpleLogin(ref:ref)

Once you have instantiated the client library, check the user's authentication status:

[authClient checkAuthStatusWithBlock:^(NSError* error, FAUser* user) {
    if (error != nil) {
      // Oh no! There was an error performing the check
    } else if (user == nil) {
      // No user is logged in
    } else {
      // There is a logged in user
    }
}];

authRef.checkAuthStatusWithBlock({ error, user in
    if (error != nil) {
        // Oh no! There was an error performing the check
    } else if (user == nil) {
        // No user is logged in
    } else {
        // There is a logged in user
    }
})

In addition, you can monitor the user's authentication state with respect to your Firebase by observing events at a special location: .info/authenticated

Firebase* authRef = [ref.root childByAppendingPath:@".info/authenticated"];
[authRef observeEventType:FEventTypeValue withBlock:^(FDataSnapshot* snapshot) {
    BOOL isAuthenticated = [snapshot.value boolValue];
}];

var authRef = ref.root.childByAppendingPath(".info/authenticated")
authRef.observeEventType(.Value, withBlock: { snapshot in
    var isAuthenticated = snapshot.value as? Bool
})

If the user is logged out, try authenticating using the provider of your choice:

[authClient loginWithEmail:@"[email protected]" andPassword:@"very secret"
    withCompletionBlock:^(NSError* error, FAUser* user) {

    if (error != nil) {
        // There was an error logging in to this account
    } else {
        // We are now logged in
    }
}];

authRef.loginWithEmail("[email protected]", andPassword: "very secret") { (error, user) in
    if (error != nil) {
        // There was an error logging in to this account
    } else {
        // We are now logged in
    }
}
