Firebase - Anonymous Authentication

In this chapter, we will authenticate users anonymously.

Step 1 - Enable Anonymous Auth

This is the same process as in our earlier chapters. You need to open the Firebase dashboard, click on Auth from the side menu and SIGN-IN-METHOD inside the tab bar. You need to enable anonymous authentication.

Step 2 - Signin Function

We can use signInAnonymously() method for this authentication.

Example

Let us consider the following example.

firebase.auth().signInAnonymously()
.then(function() {
   console.log('Logged in as Anonymous!')
   
   }).catch(function(error) {
   var errorCode = error.code;
   var errorMessage = error.message;
   console.log(errorCode);
   console.log(errorMessage);
});
