I use a third party plugin that adds Social Login option to my blog. It works very well, but I dislike that when users choose to login by their social accounts the user login names (user_login
in database) are saved in this format - "First-Second", so the first letter of the each part are capitals. My own user_login
will be "Iurie-Malai", but I would like "iurie-malai".
I know that WordPress usernames are case-insensitive, but I want that user logins to be only in lowercase. How can I do this?
