Overview: Twitch and Django Bcrypt + OAuth

Twitch combines bcrypt password hashing and OAuth for security. Bcrypt’s slow, salted hashing process thwarts mass password cracking, while OAuth tokens allow controlled, revocable access without revealing raw credentials.

In Django, bcrypt-based hashers like BCryptSHA256PasswordHasher add multiple rounds of hashing. OAuth grants tokens for services so users don’t need to continually share their password, reducing password compromise risks.

OAuth Basics

OAuth tokens decouple user credentials from API interactions. Tokens can be short-lived or scope-limited for targeted access.

Token Revocation and Expiration

Expired or compromised tokens can be invalidated quickly. This system isolates potential breaches and protects the underlying account credentials.

Why Plaintext Passwords Aren’t Stored

Storing only salted hashes prevents an attacker from seeing or brute-forcing raw passwords. Twitch can verify each user attempt by re-hashing at login.

Bcrypt in Django

Django supports bcrypt out of the box. Its iterative hashing feature makes it prohibitively slow to test millions of password guesses simultaneously.

Performance Considerations

Massive password leaks become harder to exploit because each password guess is expensive. OAuth tokens further reduce exposure by abstracting away real credentials in daily authentication flows.

Advanced Info on OAuth Flows

OAuth flows like PKCE protect native apps where storing client secrets securely is difficult. Twitch also employs refresh tokens for maintaining long sessions.

Additional Security Layers

Combined with IP checks, multi-factor authentication, and anomaly detection, bcrypt and OAuth form the backbone of a comprehensive authentication strategy.
