Using Cloudflare Firewall, you can limit access to WordPress login page for your whitelisted country.
- This would be heplful to prevent brute force attack from the outside country.
Login to Cloudflare (Select account > domain )
Go to Crypto Menu and create a new Firewall rule
Rule name: Allow Login page only for India
Country > Doesn’t equal to > India
URI Path > contains > wp-login.php
- Only whitelisted country can access login page, and non-other.
Edit: Made some corrections.
Thanks & Regards,
