Enhance Security of WordPress Backend

[S-mardii]

Our team should consider the security of accessing the backend of ODC WordPress.

There are 3 things we should put into consideration:
(1) Use the route other than the default route to login to the backend
Currently, the route to access ODC website backend, /wp_admin, which is the default route. Since the default route increases the level of vulnerability of the website, it is better to be changed other route which is less general and predictable.

(2) Add Captcha to the login page
This helps distinguish between Human and Bots

(3) Enable two-factor authentication
Make it harder to log in to our account
