How do I implement basic authentication in my application?

To implement basic authentication, you need to set up a login form that collects a username and password.

What technologies can I use for this?

You can use technologies like Node.js, Python with Flask, or PHP to handle the authentication process.

Can you show me a code example?

Sure! Here's a simple example in Node.js using Express:

const express = require('express');
const app = express();

app.use(express.json());

app.post('/login', (req, res) => {
    const { username, password } = req.body;
    // Validate credentials here
    if (username === 'user' && password === 'pass') {
        res.send('Authenticated!');
    } else {
        res.status(401).send('Unauthorized');
    }
});

app.listen(3000, () => console.log('Server running on port 3000')); 

What are the security implications of using basic auth?

Basic authentication sends credentials in an encoded format, so it's important to use HTTPS to secure the data during transmission.
