AWS Cognito alternative: For teams who've outgrown do-it-yourself auth

Looking for an AWS Cognito alternative? Logto gives you multi-tenant organizations, enterprise SSO, and a sign-in experience you fully control without Lambda glue code or a new user pool every time requirements change.

Why teams look for AWS Cognito alternatives

Cognito earned its place in the AWS stack: it lives next to your infrastructure, identity pools can hand your apps temporary AWS credentials, and the Lite tier stays cheap at scale. But auth rarely stays a checkbox. When sign-up requirements change, when business customers arrive, or when the bill changes shape again, teams realize they're maintaining a toolkit instead of shipping a product. That's usually when they start comparing.

MotivationWhat it looks like in practice
Pricing that keeps movingIn May 2024, AWS introduced billing for machine-to-machine auth that had been free; existing accounts got a 12-month exemption, and those bills arrived in May 2025. In November 2024, new tiers cut the free allowance for new accounts from 50,000 to 10,000 MAU, and new user pools now default to Essentials at $0.015 per MAU, nearly three times the Lite rate. In November 2025, AWS dropped the per-app-client M2M fee but kept charging for every token request. Each change was announced. None of them asked.
Settings you can never changeIn Cognito, sign-in identifiers, username case sensitivity, and required attributes are locked when a user pool is created, and custom attributes can never be modified or deleted. Get one wrong and the official remedy is blunt: "migrate your users to a new user pool". Auth requirements evolve; your pool configuration can't.
One rate-limit pool for your whole accountCognito request quotas apply per AWS account per region, shared across every user pool you run, so a sign-in spike in one product can throttle all of them. Raising the adjustable categories means buying provisioned capacity on top of MAU pricing. Others are fixed: password recovery is capped at 30 requests per second and machine-to-machine token issuance at 150, no matter what you pay.
B2B is a do-it-yourself projectCognito has no organization model. The official multi-tenancy guidance offers patterns to assemble yourself from user pools, app clients, or groups, and concedes that with pool-per-tenant "the development and operation effort" is high and "each user must sign up individually for each tenant". On top of that, every enterprise user signing in through SAML or OIDC costs $0.015 per month after the first 50, on every tier.
The sign-in page isn't really yoursManaged login gives you a visual editor for colors and logos, but AWS is explicit: you can't modify or localize the text, and only 12 built-in languages exist. The Lite tier is limited to the older classic hosted UI, which supports a logo and a fixed set of CSS values, with no localization at all. And a custom domain requires a certificate in US East (N. Virginia), wherever your users live.

How is Logto different from AWS Cognito?

Auth that stays reconfigurable

Logto doesn't lock your identity schema at setup. Sign-in identifiers are settings you change in the console, and user profiles carry schemaless custom data. When requirements shift from email-only to phone or passkeys, you flip the configuration; you don't rebuild the tenant and migrate every user.

Multi-tenant B2B out of the box

Logto organizations give each business customer its own members, roles, and enterprise SSO connection, with just-in-time provisioning when their users first sign in. What Cognito's best-practices guide leaves you to assemble from pools, app clients, and groups is a first-class product surface in Logto.

Pricing that holds still, and an exit that stays open

Logto's free plan covers 50K MAU and 50K tokens a month, machine-to-machine included, and Pro is $24 per month with unlimited MAU. Rate limits are per tenant, and raising them for a growing workload is a conversation with support, not a capacity purchase. Logto Cloud is a fully managed service, and it runs the same codebase as Logto's open-source version (13k+ GitHub stars). If the pricing or the roadmap ever stops working for you, you can self-host and keep going.

Is Logto the right AWS Cognito alternative for you?

We believe in honest positioning. Logto isn't the perfect fit for every AWS Cognito customer.

When you should switch to Logto

  • You're starting a new project. Cognito's free tier for new accounts is 10,000 MAU. Logto's free plan covers up to 50K MAU, and development tenants include every premium feature free of charge.
  • You're building B2B SaaS. Organizations, per-organization enterprise SSO, and just-in-time provisioning are product features in Logto, not architecture patterns you assemble and operate yourself.
  • Machine-to-machine traffic is real money for you. Cognito bills every M2M token request with no free allowance, from $0.00225 each (US East). Logto's free plan includes 50K tokens a month, and only access tokens count toward billing.
  • Your sign-in page needs your words and your languages. Logto lets you edit every phrase, add languages beyond the built-in set with 113 language tags, or replace the whole experience with your own UI.

When AWS Cognito might be a better fit

  • Your apps need AWS credentials. Cognito identity pools hand clients temporary IAM credentials for direct access to services like S3 and DynamoDB. That capability is native to AWS, and a third-party CIAM won't replace it.
  • You're grandfathered and the basics are enough. Accounts from before November 2024 keep a 50,000 MAU free tier on Lite. If built-in flows cover your needs and your pool was configured right the first time, Cognito remains the cheap default inside AWS. For what it's worth, Logto's free plan also covers 50K MAU.

Migrating from AWS Cognito: What to expect

Here's the honest part: Cognito doesn't let you export password hashes, so no vendor can promise a bulk migration where every existing password silently keeps working. Cognito itself doesn't accept imported hashes either: its own bulk import makes users reset their password on first sign-in.

Everything else moves cleanly. Export user profiles through the Cognito APIs and bulk-import them with Logto's Management API. Users who sign in with social providers or passwordless methods won't notice the switch at all.

For password users, plan either a one-time reset or a staged rollout. The right approach depends on your user base, so tell us about your setup and we'll help you plan the cutover.

Frequently asked questions

Is AWS Cognito free?

Partly. Accounts created after November 22, 2024 get 10,000 MAU free per month on the Lite or Essentials tier; older accounts keep 50,000 free MAU on Lite. The Plus tier has no free allowance. Machine-to-machine token requests are always billed, users federated through SAML or OIDC are free only up to 50 MAU, and SMS messages are billed separately through Amazon SNS.

What changed in AWS Cognito pricing?

Three changes in two years. May 2024: AWS introduced per-token billing for machine-to-machine auth, with a 12-month exemption for existing accounts that ended in May 2025. November 2024: Cognito was restructured into Lite, Essentials, and Plus tiers, the free tier for new accounts dropped from 50,000 to 10,000 MAU, and new user pools default to Essentials at $0.015 per MAU. November 2025: AWS removed the per-app-client M2M fee while keeping per-token charges.

Does AWS Cognito support B2B multi-tenancy?

Not as a built-in feature. AWS documents multi-tenancy patterns you implement yourself: a user pool per tenant, an app client per tenant, or groups within one pool. Each has documented trade-offs, from high development and operations effort to users signing up separately for each tenant. Logto models this directly with organizations: each business customer gets its own members, roles, and enterprise SSO connection.

What is the best AWS Cognito alternative?

It depends on why you're leaving. If your apps need temporary AWS credentials for services like S3, Cognito identity pools remain the native path. If you want built-in B2B organizations, enterprise SSO without per-user federation fees, and pricing that doesn't change underneath you, Logto is a strong choice. Auth0, Firebase Auth, and Keycloak are also commonly evaluated.
