Firebase Android

In this method we can also authenticate without a password, but for that we need a dynamic link.

To our happiness, Firebase also offers this service for free.

In the side menu we have Dynamic Link.

Create a link:

Then on the Authentication / Sign-in method tab, authorize the domain you just created:

In the Firebase console, open the Auth section.

And of course don't forget to activate the Sign-in method in Firebase:

When we want to authenticate a user using a phone number, we need to define SHA1 in the Firebase panel:

In this case we will use the application test sha1 in Android Studio:

In the Firebase console, open the Auth section.

And of course don't forget to activate the Sign-in method in Firebase:

we need google-services.json at our app's app level:

When we want to authenticate a user using Google, we need to create consent screen in:

https://console.cloud.google.com/apis/credentials/consent?project=project_Id

And of course we need to define SHA1 in the Firebase panel as we have done above

When we want to authenticate a user using Google, we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

We need our OAuth 2.0 client IDs:

https://console.cloud.google.com/apis/credentials/oauthclient

we need google-services.json at our app's app level:

In the Firebase console, open the Auth section.

And of course don't forget to activate the Sign-in method in Firebase:

If you haven't yet specified your app's SHA-1 fingerprint, do so now

we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

Before starting, in order to use the Play Games authentication method,

we must have a google play developer account.

We don't need to publish a game to test this method, just create one on the google play store.

Create an app in the store and define it as a game.

Now in Google Play game-related service settings.

Yes, my game already uses Google APIs.

Select the same Google Cloud Project.

And click USE, ready, now you can continue the configuration.

When we want to authenticate a user using Play Games, we need to create consent screen in:

https://console.cloud.google.com/apis/credentials/consent?project=project_Id

And of course we need to define SHA1 in the Firebase panel as we have done above

And of course don't forget to activate the Sign-in method in Firebase:

Create an app on Developer Facebook, write down the app ID and complete the setup steps

After choosing the type of application that should be Android,

go to part 3 and define the package name and the deep link and save, in our case it looks like this:

click Use this package name. And continue

4. Add your development and launch key hashes

You will need the following:

Certificate and key management tool (keytool) from the Java Development Kit

openssl library for Windows from Google

To generate a development key hash, run the following command at a command prompt in the SDK for Java folder:

After extract folder in C:/, go inside your jdk/bin folder, open CMD type cd C:\Program Files\Java\jdk1.8.0_144\bin

To find the debug.keystore.Go to drive C:\Users\computerName\.android

Keystore name: "debug.keystore"

Keystore password: "android"

Key alias: "androiddebugkey"

Key password: "android"

Hashes of keys

set Hash

Save and continue

In your Facebook dev panel settings/basic/

get the application ID and the Application Secret Key

In the Firebase console, open the Auth section.

In Facebook Login providers, we will need the application ID and the Application Secret Key

and we’ll put the OAuth redirect URI to your Facebook app configuration.

and In your Facebook dev panel fb-login/settings/ Client OAuth settings

set your OAuth redirect URI that you got on firebase

You can test using test users or only with your administrator account

If you haven't yet specified your app's SHA-1 fingerprint, do so now

we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

In the Firebase console, open the Auth section.

and activate the Twitter login method,

which will ask for two keys that we will get next from the Twitter developer panel,

note the url provided by Firebase that we will use on Twitter

Log in to your account and create a project,

to add your callback URL to your Twitter application configuration and get both keys requested in Firebase

after creating your application you will see a screen like this:

find Authentication settings

click on Keys and tokens

select your keys and use in Firebase in the requested fields

If you haven't yet specified your app's SHA-1 fingerprint, do so now

we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

In the Firebase console, open the Auth section.

and activate the Github login method,

which will ask for two keys that we will get next from the Github developer panel,

note the url provided by Firebase that we will use on Github

Log in to your Github account go to settings, to create an OAuth application

after creating the application scroll down the page until you get to Identifying and authorizing users

and set User authorization callback URL | Webhook URL that you got in Firebase

and define the other mandatory parameters as you wish

now go to Generate a new client secret, and get both keys that we will put in Firebase

If you haven't yet specified your app's SHA-1 fingerprint, do so now

we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

In the Firebase console, open the Auth section.

On the Sign in method tab, enable the Yahoo provider.

Add the Client ID and Client Secret from that provider's developer console to the provider configuration:

note the url provided by Firebase that we will use on Yahoo

In the Yahoo console, create app.

Be sure to select the two OpenID Connect API permissions: profile and email

When registering apps with these providers, be sure to register the url provided by Firebase domain for your project as the redirect domain for your app

After creating the application, take the keys and place them in Firebase

If you haven't yet specified your app's SHA-1 fingerprint, do so now

we need to define SHA1 in the Firebase panel as we have done above:

In this case we will use the application test sha1 in Android Studio:

In the Firebase console, open the Auth section.

On the Sign in method tab, enable the Microsoft provider.

Add the Client ID and Client Secret from that provider's developer console to the provider configuration:

note the url provided by Firebase that we will use on Microsoft

In the Microsoft console, follow those steps to create an app

to create app select Registers of application

Fill in the requested fields and use your callback URL that you got in Firebase

now write down the application ID (client) and let's create our Application Secret.

Fill in the requested fields.

write down the application secret now, you will not be able to see it again.

now just put the application ID and the secret on the Sign Microsoft provider in Firebase
