Looking for an Auth0 alternative? Logto helps growing teams build secure, enterprise-ready authentication without the MAU growth tax or forced feature bundling.
When we talk to teams migrating away from Auth0, the conversation rarely starts with technology. Auth0 is a stable, mature product, and everyone knows it. The complaints start with pricing models and structural limits.
| Motivation | What it looks like in practice |
|---|---|
| The MAU "growth tax" | As your monthly active users (MAU) grow, your bill grows with them, even if most users only log in once a month. Teams often face steep price jumps when moving off the free tier or crossing MAU thresholds. |
| Forced feature bundling | Auth0's tiered pricing often means paying for an entire suite of features just to access one specific capability, like custom domains or a few more enterprise connections. |
| Hard limits on B2B growth | Auth0's self-service B2B plans include only 3–5 enterprise SSO connections ($100/month each beyond that, hard-capped at 30), and each Auth0 organization can enable at most 10 connections. Multi-brand and B2B2C companies with dozens of connections end up splitting customers into duplicate organizations, or they get pushed into a custom Enterprise contract. |
| Metered M2M tokens | Machine-to-machine (M2M) tokens are strictly metered: 1,000 per month on Free and Essentials plans, 5,000 on Professional, and more only through paid add-ons. One misconfigured batch job can burn through the whole allowance and turn into a surprise bill or an interrupted service. |
Instead of charging for every user sitting in your database, Logto's paid plans are billed by actual usage: only access tokens count, while ID and refresh tokens are excluded. If a user doesn't log in, you don't pay for them. And the free plan covers up to 50K MAU.
Logto Cloud is a fully managed service, and it runs the same codebase as Logto's community-driven open-source version (13k+ GitHub stars). Start on the cloud for convenience, knowing you can self-host later if your compliance or economics ever demand it.
Enterprise SSO, MFA, and multi-tenant organizations are flexible add-ons rather than a massive enterprise bundle. You pay only for the enterprise features you actually need to close your next deal.
We believe in honest positioning. Logto isn't the perfect fit for every Auth0 customer.

The biggest fear when switching auth providers is the dreaded "please reset your password" email. With Logto, your users never need to see one.
Logto supports importing password hashes directly, including Bcrypt, Argon2, MD5, SHA1, SHA256, and PBKDF2. A legacy option accepts any other hash format supported by Node.js. Export your user data from Auth0 and bulk-import it into Logto with the Management API.
When users log in for the first time after the migration, Logto validates the old password hash and automatically re-hashes it with the modern Argon2 algorithm. Your users won't notice a thing.

The "best" alternative depends on your needs. For teams looking for transparent, usage-based pricing with the flexibility to self-host, Logto is a strong contender. Teams deeply embedded in the Microsoft ecosystem may consider Entra External ID, while purely Next.js-focused projects often look at Clerk.
In most growth scenarios, yes. Logto's free plan covers up to 50K MAU, and paid plans charge by access tokens issued rather than monthly active users, so you don't pay a tax for dormant users. Exact costs depend on your usage patterns and the enterprise features you need.
Yes. Most teams use Logto Cloud, the fully managed service. But unlike Auth0, Logto also has an open-source version you can self-host on your own infrastructure as a single lightweight service.
Yes. Logto supports both SAML and OIDC enterprise SSO connections, available as a modular add-on. No custom enterprise contract required.
