Auth for B2B SaaS: it's not like auth for consumer software


Auth for business software (B2B) shouldn’t look the same as auth for consumer software (B2C). In many cases, it actually can’t work the same way.

At the extreme end of scale, Meta, reports 3.35 billion Daily Active People (DAP) across its different applications (Instagram, WhatsApp, Facebook, etc.). Or we might see a repeat of the 2008 Terry Childs incident: a man locked out all other San Francisco municipal employees from accessing parts of their internal network. Sure, support for Okta and Entra gets you pretty far, but people use all kinds of IDPs in the real world, from reasonable options like old-school ADFS or Sailpoint to chaotic custom builds that no one’s touched since 2005.
