My top 3 Auth0 alternatives
By Edouard Rosenblum, Co-founder @Secret
Stytch
When developing an application as a multi-tenanted B2B Software-as-a-Service, Stytch has provided a clean mapping of the way my application functions. This includes the Organizations, Sessions and Role-Based Access Control within the same platform. I am pleased to see that I can implement Organization level Primary / Secondary Authentication Policies. And use Just-In-Time Provisioning Controls (by Email Domain and by SSO Connection), which enable new Enterprise customers to onboard using the built-in invite functionality – Without having to develop custom "Invite" Plumbing.
Firebase
For consumer apps (especially mobile), I reach for Firebase because the provider menu is practical: email/password, email link, phone number, and federated logins like Google, Apple, GitHub, and Microsoft. I also like that multi-factor isn’t an afterthought (SMS MFA and TOTP MFA are documented paths), and I can drive authorization with custom claims in ID tokens. On pricing, phone auth is billed per SMS, while “other authentication services” can be used with Identity Platform, with no-cost MAUs up to 50K (and SAML/OIDC up to 50 MAUs).
Okta
When the requirement is “enterprise CIAM with procurement-friendly terms,” I look at Okta because the Customer Identity offering is positioned around an Enterprise base platform and formal SLAs. The published starting point is $3,000 per month (billed annually), and it explicitly calls out unlimited OIDC and outbound SAML apps plus a 99.99% uptime guarantee. I also pay attention to operational limits: the Integrator Free Plan notes a default rate limit of 100 authentications/minute, while paid plans start at 600 authentications/minute with a DynamicScale add-on available.
List of Alternatives to Auth0
Here are some of Auth0's top competitors in the Security category: Stytch, Firebase, Okta or Supabase.
The Stytch platform allows you to manage authentications and authorizations in a simple and efficient way. This allows you to centralize your needs and create smooth and enjoyable integration and authentication experiences.

Why is Stytch a good alternative to Auth0?
Stytch is the alternative I pick when the team is shipping a B2B SaaS and the “hard parts” are SSO/SCIM + multi-tenant authorization, not just login screens. I like that the baseline product vocabulary is built around Organizations and org-level policies, so I can model each customer as an org, then attach SSO connections (and optionally SCIM) to that org instead of inventing my own abstraction. The free tier is unusually concrete for early-stage products: 10,000 MAUs, unlimited organizations, 5 SSO/SCIM connections, and 1,000 M2M tokens, so I can test real enterprise workflows before I’m forced into a contract conversation. It’s also a fit for teams that need “some risk controls later,” because the pricing page calls out optional fraud/risk prevention add-ons (including device fingerprinting).

Why is Firebase a good alternative to Auth0?
Firebase is the alternative I choose when I want authentication to feel like another app SDK, not a separate identity product with its own mental model. If I’m building iOS/Android/web clients, I can mix email link auth, phone number sign-in, and common OAuth providers (Google, Apple, GitHub, Microsoft) without designing a custom protocol surface area. For authorization, I lean on custom claims in ID tokens and manage sessions via session cookies when needed, which keeps the “authn vs authz” boundary very code-centric. On cost control, it’s helpful that the pricing page separates phone auth (billed per SMS) from other auth services with Identity Platform, and it explicitly lists a no-cost MAU allowance up to 50K (plus a small no-cost tier for SAML/OIDC MAUs).
What are the differences between Firebase and Auth0?
Firebase Authentication is “SDK-first,” while Auth0 is “authorization-server-first.” In Firebase docs, the navigation is literally organized around concrete sign-in methods (password auth, email link auth, federated identity/social, phone number, anonymous auth), plus admin tasks like session cookies and custom claims. If you need enterprise identity providers, Firebase points you to SAML and OpenID Connect support (with Identity Platform), and it also documents audit logging and multi-tenancy as part of the Identity Platform upgrade path. Pricing is also structured differently: phone auth is billed per SMS, and Identity Platform shows no-cost MAUs up to 50K (and SAML/OIDC up to 50 MAUs), whereas Auth0’s self-serve plans are presented as monthly subscriptions with MAU quotas (Free up to 25,000 MAUs, then paid tiers). Auth0’s “hosted login” customization story (Universal Login templates) is more explicit than Firebase’s default UI approach.
Okta brings value by providing a secure and reliable identity management platform for businesses. With Okta, companies can effectively manage and control access to their applications and data, ensuring that only authorized individuals have the right level of access.

Why is Okta a good alternative to Auth0?
Okta is a good Auth0 alternative when the buyer is an enterprise security org that wants the identity layer packaged as a base platform with contractual guarantees. The pricing page is clear that Customer Identity starts with an Enterprise base platform at $3,000/month billed annually, and it emphasizes enterprise-grade SLAs (including a 99.99% uptime guarantee). That’s attractive when I’m supporting RFP language that literally asks for uptime commitments and formal support plans. Okta also feels designed for environments with a lot of app integration surface area: the base benefits include unlimited OIDC and outbound SAML apps and “robust Okta APIs,” which maps well to portfolios that include both modern and legacy apps. Finally, if I expect high authentication throughput, I appreciate that Okta publishes default authentication rate limits (100/min on the Integrator Free Plan, 600/min on paid plans) and explicitly points to DynamicScale as the lever to raise them.

AWS gives us the flexibility to run applications, storage, databases, and background workloads without committing to a fixed infrastructure too early. Services such as EC2, S3, managed databases, container platforms, and serverless options make it possible to choose the right level of control for each product stage. It works well for development-driven teams that need reliable infrastructure and room to scale as demand changes. We use Google Workspace for internal collaboration, documentation, and business communication, while AWS supports the underlying technical workloads and deployment environment. The main challenge is cost governance: the service catalog is broad, so monitoring usage and setting budgets from the start is essential.

JumpCloud is a cloud-based directory service that enables IT admins to manage users, devices, and access to IT resources. It supports various platforms like Mac, Linux, and Windows. It offers features such as single sign-on (SSO), multi-factor authentication (MFA), and system management.
-

-

-

Why is JumpCloud a good alternative to Auth0?
I believe JumpCloud Directory Platform is a great alternative to Auth0 due to its comprehensive, cloud-based directory services. JumpCloud not only provides user authentication and identity management but also extends its services to device management. This is particularly beneficial for businesses with remote or distributed teams as IT admins can manage user access and devices from anywhere. In addition, JumpCloud supports a wide range of protocols including LDAP, SAML, RADIUS and RESTful APIs, which makes it versatile for different application needs. It also offers multi-factor authentication for enhanced security. While Auth0 is excellent for single sign-on and identity management, JumpCloud's wider range of services offers more control over the IT environment. Therefore, if you're looking for an all-in-one solution for user and device management, JumpCloud could be a more suitable choice.
What are the differences between JumpCloud and Auth0?
I have found some key differences between JumpCloud Directory Platform and Auth0. JumpCloud is primarily a cloud-based directory service that enables IT admins to control user identities and their access to virtually all resources they need, including systems, applications, files, and networks. It offers a comprehensive solution that replaces traditional on-premises directory services like Active Directory or LDAP.
On the other hand, Auth0 is an identity management platform for application builders. It provides a secure, highly available, enterprise-grade platform that secures billions of log-ins every year. While it does offer Single Sign-On (SSO) and multifactor authentication features, it's more focused on providing developers with easy-to-use tools to authenticate and authorize users in their applications.
So, while both offer identity and access management solutions, JumpCloud provides a broader range of IT admin capabilities, while Auth0 focuses more on developer needs.

Why is Dashlane a good alternative to Auth0?
I believe Dashlane is a great alternative to Auth0 due to several reasons. Firstly, Dashlane is not only an identity provider but also a password manager. This means it can securely store and fill in passwords for various websites and applications, thereby reducing the need to remember complex passwords. Secondly, Dashlane provides a user-friendly interface that makes it easier for users to manage their online identities. Furthermore, it offers additional features such as dark web monitoring and VPN for WiFi protection which are not available in Auth0. Lastly, Dashlane's pricing is more flexible, allowing users to choose a plan that best fits their needs. Therefore, for individuals or businesses looking for an all-in-one solution for their password management and online security needs, Dashlane could be a better choice.
What are the differences between Dashlane and Auth0?
I have found that Dashlane and Auth0 are two distinct software solutions with different functionalities. Dashlane is a password manager that securely stores your online passwords and personal information. It helps in generating strong passwords, auto-filling forms, and providing alerts about breached sites. It's primarily focused on personal or business password security.
In a slightly different way, Auth0 is an identity management platform for developers. It provides a secure and easy-to-implement solution for adding authentication and authorization services to applications. It supports various identity protocols like OpenID Connect, OAuth2, and SAML. Auth0 is used by developers to integrate security features into their applications and services.
So, while both offer security solutions, Dashlane is more focused on individual password management and Auth0 is geared towards providing developer tools for application security.

Why is Bitwarden a good alternative to Auth0?
I find Bitwarden to be a compelling alternative to Auth0 for several reasons. First, Bitwarden is open-source, which means its code is available for public scrutiny and it has a community of developers constantly working on improving its security. This transparency boosts confidence in the product's integrity and security. Second, it offers end-to-end encryption of passwords, which ensures only the user can access their stored passwords. Third, Bitwarden allows unlimited password storage across multiple devices at no cost, whereas Auth0 charges for this service. Lastly, Bitwarden provides options for self-hosting, giving users more control over their data. Overall, for individuals and businesses looking for a reliable, secure, and cost-effective password management solution, Bitwarden presents a viable alternative to Auth0.
What are the differences between Bitwarden and Auth0?
I have found that Bitwarden and Auth0 are fundamentally different in their functionalities. Bitwarden is essentially a password management tool. It securely stores all your passwords and other sensitive information, making it easier for you to log into different platforms without having to remember all your credentials. It also offers features like password generation and auto-fill.
In a slightly different way, Auth0 is an identity platform for developers. It provides a secure and easy-to-integrate solution for managing user authentication and authorization. With Auth0, developers can implement various authentication scenarios in their applications without having to write complex code or worry about security issues.
In essence, while Bitwarden focuses on personal password management, Auth0 is geared towards providing application-level user authentication solutions.
