Objective:
Understand the limitations of brute-force attacks on OAuth-based authentication systems like Clerk.
Key Insight:
Hydra cannot perform brute-force attacks on OAuth logins because authentication is handled via third-party redirects (e.g., Google). There is no form-based login endpoint such as /api/auth/signin, so tools like Hydra and manual POST request manipulation will not work.
Why Brute-Force Fails:
No /api/auth/signin POST endpoint for username/password
Clerk handles login using OAuth redirect flow, not local login fields
Hydra and other tools can't brute-force a redirect
Conclusion:
Brute-force tools like Hydra won’t work against Clerk’s OAuth login flow.
