Auth · Sessions · Real users

Auth that holds when someone else logs in.

It works until real users show up. Login, roles, or “it remembers me and nobody else” is usually the first break.

We review authentication and authorization: how sessions are stored, what the client can see, OAuth callback URLs, Replit Auth vs a provider you wired, and whether permissions actually match the routes.

Agent often ships a login that works in preview with one account. Production needs env, a real redirect URI, password reset, and the difference between “logged in” and “allowed to see this row.”

Security work sits in the same review — secrets, API endpoints, and who can hit them. We don't bolt on a second auth system because the first one looks generated.

What we do

  • 01

    How you sign in today

    The live flow, the callbacks, and the env production is missing.

  • 02

    Who can see what

    Roles, row access, and admin paths that Agent left open.

  • 03

    A fix you can ship

    Written scope. Then the change. Then domain and deploy if that's still waiting.

What we skip

  • We don't replace working auth for a trendier provider without a reason.
  • We don't leave secrets in the client to make login “easier.”
  • We don't skip the Launch Review on a “quick auth fix.”

Frequently Asked Questions

Can you improve the security of my Replit application?
Yes. We can review authentication, authorization, API endpoints, secrets and environment variables, database access, user permissions, dependencies, input validation, and other security-sensitive areas. For existing applications, we can also perform a focused security and architecture audit before making changes.
Can you fix a Replit app that isn't working?
Yes. We troubleshoot Replit applications with frontend, backend, database, authentication, API, deployment, performance, and configuration issues. We first identify the root cause and then recommend the safest and most efficient way to fix it.
Do I need to give you access to my Replit account?
Not necessarily. The access required depends on the project. We will only request the minimum access needed to review or work on your application, and we can discuss the safest way to provide project access before development begins.
How do I get started with a Replit expert?
Send us a short description of your project, what you have already built, and what you need help with. If you already have a Replit project, you can also share its current status. We'll review your requirements and recommend the best next step, along with an estimated scope, timeline, and cost.
