Enhancing User Authentication in Laravel API: Login with Email or Registration Number

User authentication is a critical aspect of any web application. Often, we need to provide flexibility in how users can log in to our systems. In this guide, we address a common problem faced by developers: how to modify your API to allow users to log in using their email or a registration number.

The Problem: Limited Login Options

In a typical Laravel application, you might have an API setup that only allows users to log in with their email addresses. While this may work for many, some users might prefer using their registration numbers, or might not have access to their email at the moment.

The original login code might look like this:

This method only allows users to authenticate using their email and password combination.

The Solution: Modify the Login Function

To enhance the user experience and provide options for logging in, we need to make some adjustments to our login method. The changes essentially check whether the input is formatted as an email or a registration number and authenticate accordingly.

Step 1: Validate the Input

Use filter_var to determine if the input provided is an email address. If it is not, consider it as a registration number.

Step 2: Update the Authentication Logic

The modified login logic could look like this:

Breakdown of Changes

Identity Check:

The line $identity = filter_var(request('email'), FILTER_VALIDATE_EMAIL) ? 'email' : 'number'; checks if the provided input is a valid email. If it is, it uses 'email' as the key; otherwise, it assumes it’s a registration number.

Attempt Login:

The Auth::attempt() method now dynamically uses either 'email' or 'number' based on the earlier check, allowing for a more flexible login process.

Returning Response:

If authentication is successful, a token is created, and a success response is returned with the token. If it fails, an unauthorized response is provided.

Conclusion

By implementing the above changes, you allow a more versatile user authentication system that can cater to different user preferences. Users can now log in using either their email or their registration number, enhancing overall usability.

This simple modification can make a significant difference in user experience, leading to improved satisfaction and engagement with your application.
