login page address

If you’re referring to the rename login page, it is stored in WordPress options table.
Look for the row with “aio_wp_security_configs” and then look inside the option_value field and find the paramater “aiowps_login_page_slug” which should have the value following it.
Similarly, if you are referring to the cookie based brute force feature, it is same as above except you will look for the “aiowps_brute_force_secret_word” parameter to get the value.
Note: for rename login page if you have permalinks enabled your login URL will look like:
yoursite.com/secret_slug

If permalinks are set to plain:
yoursite.com/?secret_slug

For cookie based feature:
yoursite.com/?secret_slug=1
