Auth0 vs OneLogin

Auth0 and OneLogin are both developer identity / ciam solutions. Auth0 developer-first identity platform for customer authentication and CIAM, while OneLogin cloud IAM platform with SmartFactor Authentication and cost-effective pricing. The best choice depends on your organization's size, technical requirements, and budget.

Choose Auth0 if best developer experience in the identity industry with comprehensive SDKs is your priority and development teams building customer-facing applications that need flexible, API-first authentication with extensive SDK support and customizable login experiences. Choose OneLogin if more affordable than Okta with comparable core SSO and MFA capabilities matters most and mid-market organizations looking for a full-featured cloud IAM platform at a lower price point than Okta with straightforward deployment.

OneLogin starts at SSO $2/user/mo; Advanced $4/user/mo; Professional $8/user/mo (per-user tiers). Auth0 starts at Free up to 25,000 MAUs; B2C paid from $35/mo; B2B paid from $150/mo (per monthly active user (mau)). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply Auth0 is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether OneLogin supports importing your existing configs or policies. That's usually the biggest time sink.
