Max Retry
Max retry defines the maximum number of failed login attempts a user (or IP) can make within a certain time window. After exceeding this limit, further attempts are blocked temporarily or permanently, depending on policy.
Why Use Max Retry?
- Prevent brute-force attacks
- Protect user accounts
- Reduce load on authentication systems
Example Settings:
| Parameter | Value |
|---|---|
| Max Retry Count | 5 attempts |
| Time Window | 15 minutes |
