Build API authentication - Basic Auth, Bearer Tokens, and JWT authentication. You'll see exactly how each method works, their security trade-offs, and why JWT became popular for modern APIs.
This is the hands-on companion to previous authentication explanation video (https://youtu.be/I747kI_y9eQ), but you can follow along even if you haven't watched that—I explain everything as I code.
What You'll See Built:
→ Basic Auth implementation (and why base64 encoding isn't encryption)
→ Bearer token system with session storage and instant revocation
→ JWT authentication with stateless verification
Key Demos:
→ Decoding Basic Auth credentials in real-time
→ Revoking bearer tokens instantly from the database
→ Comparing database lookups vs stateless JWT validation

Who This Is For:
Perfect for junior to mid-level developers who want to understand authentication by building it, not just reading about it. If you've ever wondered how login systems actually work under the hood, this is for you.
