WordPress has a feature that allows a website to have multiple users. This would be a perfect option if you’re working on a group project that uses one website.
From there, click ‘Add New’ under the users section.
Fill out all the information you’d like, specifically the username, email, password, and user role. You can designate specific roles to specific people, and they will be allowed to see specific actions. You can read more about user roles here: https://themeisle.com/blog/wordpress-user-roles/
After yo’ve filled in the information, click ‘Add New User.’ This will add the user to the site. They’ll get an email confirming the addition with instructions to login as well.
