Vanilla 2.6 is here
! It includes security fixes and requires PHP 7.0. We have therefore ALSO released Vanilla 2.5.2
with security patches if you are still on PHP 5.6 to give you additional time to upgrade.
I have searched but was unable to find anything related to this. in the admin dash clean install of 2.5 vanillaconnect click the add provider button.. it says under client id there is a button at bottom of page to generate one, but the button is not there.
