Pros & Cons

Auth0

Pros

Battle-tested enterprise auth with every compliance certification you'd need to close enterprise deals (SOC2, HIPAA, etc.)+163
The rules and actions pipeline lets you add custom logic to every auth step — useful for things like provisioning users in your database on first login+141
Every social provider, SAML IdP, and enterprise connection you could need is supported and well documented+128
Organizations feature handles multi-tenancy with per-org branding and connection settings which is essential for B2B+117

Cons

Pricing is confusing and the free tier limit of 7,500 MAU sounds generous until you hit it and face a $23/mo minimum with rapid escalation at scale
