It's always best to contact a site's support department before setting up a spouse's account. Some do not allow more than 1 account per household. I did contact Bovada
about my husband setting up an account, and if they would allow it. They said that it is not allowed, however, I could put him on my account as an authorized user. We both have Carbon and ACR accounts, but I know on Carbon at least, we cannot both be logged into our accounts at the same time. Haven't really been online at the same time for ACR.
