Brute force protection with Redis
Protect against brute force attacks by enabling config.brute_force_protection and the redis strategy.
This will return an 429 Too Many Requests error after the fourth failed login attempt.
For a complete tutorial, see Protect against brute force attacks with basic authentication.
Prerequisites
- A Consumer with a username and password
Environment variables
-
