Organization-first Data Model

B2B applications need to strictly separate auth policies and user data among several organizations
Multi-tenant Authentication
Enterprise SSO
Large organizations IT admins expect custom SSO, IdP-initiated SSO, map user attributes with their IdP systems
Enterprise SSO

Enterprise IT admins prefer to centrally configure auth settings and administer users in their org

B2B auth platforms need to adhere to security frameworks to safeguard org and user data

Consumer-centric auth solutions fall short of B2B needs

Gatekeeping features for enterprise plans
I want to warn people: if you want your customers to log in with SAML, Azure AD, etc., you must be on the enterprise plan. Enterprise starts at +$35k.
G2 Review
Extensive development
time & effort
I found the documentation hard to understand at first, but after a few approaches I managed to work out my own workflow and then create internal documentation for my team.
G2 Review
Difficulty in implementation
Making a multi-tenant application in Auth0 is difficult. Implementation of SSO, identity features in B2B applications is a bit strange.
Hacker News
You end up paying a premium
The product somewhat works, but there are better alternatives and I would not recommend using them unless you are ok paying a premium not getting anything in return.
G2 Review
Not out-of-the-box
ome devs however have reported a learning curve, particularly when configuring advanced features or customizing authentication flows.
G2 Review
Not built for scale
Tangentially, if you’re a B2C startup like an app, avoid using Auth0. Their pricing starts out cheap but once you reach 10000 MAUs, it will go from it will go from $X00 a month to a 3 year contract for $X00000.
