Authentication is simply the process of proving who you are. In the world of web services, Basic Authentication is the oldest and simplest method. It uses a straightforward Username and Password combination to let you through the door.
Why Is It Called "Basic"?
It's called basic because it doesn't require cookies, session IDs, or complex login pages. The credentials are sent directly in the HTTP Header of every request you make.
- Easy to implement for developers.
- Supported by every browser on the planet.
- Works perfectly with simple testing tools like Postman.
The "Vulnerable" Part
Here is the catch: Basic Authentication encodes your password in a format called Base64. Base64 is not encryption—it can be easily decoded by anyone who intercepts the message. This is why you must always use HTTPS to protect the connection.
