The "Stage" is the page that you share with your client to give them access to app releases, live builds and and other project related material you want to make available.
The stage page features:-
The stage page uses a random 40 character token to obfuscate url and prevent guessing. For example:-
Now when the user goes to the stage page they will be required to enter the password.
The stage page will authomatically create a plist for ipa installs of the apps. The user simply needs to click on the app link and the installation will begin.
Installs will only work for ipas that have been signed with a valid adhoc or enterprise provisioning profile.
The client stage page can be branded to either your clients brand or your owner brand as an external vendor. Please note this feature is only avaible to users on the "Agency" plan.
More information on branding is available here.
