AWS Cognito Support
AWS Cognito support, troubleshooting and optimization.
Cognito handles sign-up and sign-in for many apps. Token handling, hosted UI, federation and migration are where teams most often need help.
Common Cognito problems we fix
The Amazon Cognito issues our engineers see most often, and how we resolve them.
Cognito invalid token or token expired errors
Access, ID and refresh tokens have separate lifetimes and audiences. We validate JWTs correctly (issuer, audience, signature) and implement refresh flows.
Cognito user pool migration
Moving users from another system requires a user migration Lambda trigger or bulk import, since passwords cannot be exported from most systems. We design a seamless migration.
Cognito social and SAML federation problems
Redirect URIs, attribute mapping and clock skew break federation. We configure identity providers and mappings correctly.
Cognito email and SMS delivery
Default email limits, SES sandbox status and SMS spending limits stop messages. We configure SES and SNS properly.
Securing APIs with Cognito authorizers
We connect user pools to API Gateway authorizers and map groups and scopes to permissions.

Frequently Asked Questions
User pool or identity pool?
User pools authenticate users and issue tokens. Identity pools exchange identities for temporary AWS credentials. Many apps need only a user pool.
Can you migrate our users to Cognito?
Yes, using a lazy migration trigger so users keep their passwords or bulk import with reset flows.
Does Cognito support MFA?
Yes, with SMS, TOTP authenticator apps and adaptive risk-based options.
