Can I give another person authorization to edit my Wix site?
Currently, we do not have a feature which enables multiple users to edit a single site.
Any person who has your Wix login details (registered email and password) will be able to log in to your account and edit your site. To allow easy access to your Wix site Editor, you can add a Webmaster login.
Make sure to give your password to authorized people only.
Your site may only be edited from one computer at a time. If you have multiple users editing your site from different computers, make sure that each user logs out of the account completely before the next user begins.
