1)  Open the Plugin General Settings Tab and add your IP address to the whitelist field (if necessary) and click save changes. You can see your current  IP address at that page.

2) What Happens if someone not whitelisted try to login (or i change my ip)?

Your login page will request your wordpress user email and will send to you one alert email someone not whitelisted just made login. If the email is correct, the login go through. Then, by security, not show your wordpress user email at your page.

To avoid receive the alert email, just add your IP to whitelist. Please, read above (1).

The email alert will be send to your wordpress user email. You can change this email by click over the tab email settings at the plugin management page.

3) If you forget your wordpress email, just to confirm,  you can click over the Forgot the password link at wordpress login page and they will send you one email.

4) If necessary, (you are unable to login) you can remove this plugin by FTP. Go to folder: wp-content/plugins/ and remove the folder AntiHacker with all files.
