B2B applications need enterprise-grade authentication

Organization-first Data Model
Multi-tenant Authentication
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
Centralized User Controls
Enterprise IT admins prefer to centrally configure auth settings and administer users in their org
Centralized User Controls
Security Frameworks
B2B auth platforms need to adhere to security frameworks to safeguard org and user data
Security Frameworks

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.
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.
Difficulty in implementation
Making a multi-tenant application in Auth0 is difficult. Implementation of SSO, identity features in B2B applications is a bit strange.
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.
Not out-of-the-box
ome devs however have reported a learning curve, particularly when configuring advanced features or customizing authentication flows.
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.
