We currently own siteA.com
and have a pretty big user base.
We are now planning to introduce siteB.com
and siteC.com
into the mix. Since we want to end up with a "network of sites" and make things easy for the users, login credentials on siteA
should work on siteB
and siteC
and so on.
Essentially, one login should work across all sites. If someone registers on siteC
, he should be able to use the same credentials on siteA
and siteB
.
Since we are not ubiquitous like Google or Facebook, it is not apparent that one set of login credentials will work across all sites.
What sort of affordance can we communicate to the user during registration and login that one set of login credentials will work across all sites?
It needs to be a flexible solution as it is possible that we will introduce siteD
, siteE
, etc in the future.
