In this episode, we're going to build an anonymous authorization service with Angular 4 and Firebase.
This feature will allow user to start using your app without going through the typical OAuth sign in or email password registration process.
This approach is also called lazy registration or gradual engagement.
It works by creating a session using only the user ID.
If a user signs out without updating more account details, they will be unable to log back in and retrieve any data that they created.
At this point, it's assumed that you have the AngularFire 2 package installed and bootstrapped into your application.
If not, go to the docs or check out this video.
If starting from scratch, generate the auth service.
I'm actually gonna be building upon the auth service from my previous OAuth tutorial, so I recommend checking out that video first if you haven't already.
Head over to your Firebase project and enable the anonymous provider.
1st, make sure to subscribe to the Firebase auth state in the constructor.
Then write a function to log in the user with the anonymous provider.
And let's also add a TypeScript Getter to see if a user who's currently logged in is anonymous or not.
This will be useful when displaying content specifically for anonymous users in the template.
Now we can inject the service into our components to log in users anonymously.
In this case, we just bind the function to the click event of any button or link in the template.
When the anonymous user decides to upgrade, you'll need to transfer the account data to a new account or somehow link the 2 accounts together.
The Firebase web API supports account linking, but in order to do this, you would need to bypass the AngularFire 2 package.
As an alternative, You can simply create a new account and then transfer the user's data to it.
Assuming your data is nested under a user ID, Here's how you could map it to a new account.
The function works by taking a snapshot of the data nested under the anonymous ID, Then it copies that data to the new account after the user successfully logs in with Google.
That's it for anonymous auth.

The speaker explains the use of an anonymous authorization service with Angular 4 and Isabel, which allows users to start using their app without the usual process of registration. They also mention the use of the Ross authorization service and the importance of injecting the code into their components. The speaker provides instructions on how to link accounts and suggests mapping user data to a new account if the new user decides to upgrade.
Anonymous Authentication with Angular and Firebase - Lazy Registration
https://angularfirebase.com/lessons/angular-firebase-authentication-tutorial-anonymous-auth/ In this episode were going to build an Anonymous Authorization service with Angular 4 and Firebase. This feature will allow a user to start using your app with going through the typical OAuth signin or Email Password registration process. This approach is also called lazy registration or gradual engagement. 

It works by creating a session using only a user ID (UID). If the user signs out without updating more account details, they will be unable to log back in.

At this point, it is assumed you have the AngularFire2 package installed and bootstrapped into your app. If not, go to the docs or checkout this video. 

STEP 1 - Generate the Auth Service

If starting from scratch, generate the Auth Service. I'm going to be building upon the auth service from my previous OAuth tutorial and I recommend checking that video out first.

STEP 2 - Activate Providers in Firebase

Head over to your firebase project and enable the anonymous provider.

STEP 3 - Building the Service

First, make sure to subscribe to the FirebaseAuthState in the constructor. 

Then, write a function to login the user with the Anonymous provider. 

Let's also add a TypeScript getter to  see if a logged in user is anonymous. This will be useful when displaying content specifically for anonymous users. 

STEP 4 - Create a Component

Now we can inject the service into our components to login users anonymously. In this case, we just bind the function to the click event of a button.  

STEP 5 - Upgrading the Account

When an anonymous user decides to upgrade, you will need to transfer the account data. The Firebase web API can do this, but you would need to bypass the AngularFire2 package. As an alternative,you can create a new account, then transfer the User's data to it. Assuming your data is nested under a User ID, here's how you could map it to a new account. 

This function works by taking a snapshot of the data nested under anonymous ID, then copies it to the new account after the User logs in with google. 

That's it for Anonymous Auth. Check out the full article for more details and I'll see you next time.
