Configuring Storefront Sites
New sites require some level of access control. Many use a single shared password for all users. Using a Business Manager login with the functional permission provides a much higher level of security and access control, in particular with frequent password renewals and employees leaving an organization.
For any services requiring access to the protected site, a Business Manager login is also strongly recommended. However, if the password expiration cycle is problematic, the shared password option provides a low-maintenance access control mechanism.
Note: You can use the shared password for some of the users
by simply setting the generic password. It doesn't deactivate the
protection that is configured via Business Manager user
logins.
