I have the email of a wordpress I would like to pentest but don't know how to obtain the password? Anyone have any ideas on how to do this?
Much appreciated, if possible maybe we can work together..

You can use Hydra or WPScan.

Either use a cracker to try to break the password or see if the WP site has any vulnerable plugins/themes.

Look to see if there are any vulnerabilities in any plugins that they might be using. If not you can use WPScan to try to launch a dictionary/bruteforce attack against those credentials.

Another scanner you could try is CMSmap. But definitely search for vulnerabilities before trying any brute methods.
