As the owner of an MV account/site, you should always be using the Admin Login Page to access your account. 

Your Admin Login Page is found by adding '/admin' to your MV site's link as shown in this example: 

yoursubdomain.vipmembervault.com/admin

From this page, you can also reset your admin password should you have forgotten it. Resetting your admin password can only be done on this page. 

You can also access your admin login page from the general sign-in area on your site's main page by clicking 'Sign-In' and then clicking the 'admin login' prompt. 

Questions? Reach out to us at hello@membervault.co, via the chat support within your Admin account or within our FB Group, The MV Collaborative.
