Don’t do this.

In the information security field this is called security through obscurity. You are obscuring the location of your wp-admin or WordPress login page so that they are not where they normally would be. 

While this technique *can* defeat bots, we are reluctant to recommend it.

WordPress is built to use the wp-admin directory. Developers of themes and plugins expect you to be using wp-admin. When you change this, you run the risk of breaking WordPress or introducing security exploits.

A far better security measure would be to introduce "Two factor authentication" (2FA).
