Password recovery in wookormers based on user (phone) metadata?

Question

WordPress

I did authorization and registration by phone, but the recovery does not work, because I can’t find a filter with which you can get the user by phone number at the right time. When authorizing, the woocommerce_login_credentials filter helped, and when restoring, looking at the skrinshoter.ru/s/130620/ZTkm8zWO?a

function, it turns out that you can’t filter $_POST['user_login'] or is it somehow possible?

And in general, what method do you use to find suitable hooks and actions, given that for many of the especially wookorers there is no description even in English? in addition to the method, find a code example in English and rewrite it for yourself ...
