Likelihood to Recommend
I would not strongly recommend it for single users, who don't need to share access to others.
Bitium from the relatively new company (2012) of the same name is an identity and access management (IAM) platform for SMBs / mid-market companies featuring single sign-on (SSO), automated account creation and provisioning aids, directory integration, extra security features (e.g. two-factor authentication) and analytics.
Pricing starts with core features for $2 per user per month with the Business Edition, or with expanded features for $4 and $6 per user per month with the Business Plus and Unlimited editions, respectively.
