I will handle all necessary backend configurations and ensure that FastAPI-Users works perfectly with your database setup for secure and scalable user management. I’ll ensure a smooth integration into your existing platform and provide full technical documentation along with the necessary setup instructions. Looking forward to discussing the details! Best regards, Juan

@codefusion53

Hello. I propose developing a secure and maintainable user management system using Python, FastAPI, and PostgreSQL with SQLAlchemy, fully compatible with your existing web application. The system will leverage the FastAPI-Users library to handle authentication, login/logout flows, and admin-driven account management. As per your requirements, user accounts will be created and managed exclusively by an admin, with no self-registration or password reset features. Authentication will be implemented using Basic Auth initially, with potential support for Single Sign-On (SSO) integration for enterprise-level login. The solution will include a login landing page designed to be easily embedded into your current frontend framework. All user credentials and sessions will be securely managed, adhering to best practices for password hashing and token management. The backend will provide clear RESTful endpoints for admin account management and user login status monitoring. I will also ensure the codebase is modular and well-documented, allowing seamless future enhancements such as SSO or multi-role management. Regards, Justin.

@RusianD

Hi there, I can deliver a working, drop-in FastAPI + Postgres (SQLAlchemy) authentication and user management example using fastapi-users, including a simple login landing page and admin-managed accounts only (no self-registration, no password reset). I’ll implement secure login/logout, session or token handling appropriate for your web app, and an admin-only user management flow (create/disable users, set roles/permissions) with clean structure so it integrates seamlessly into an existing project. I’ll also address the “Basic Auth” vs “SSO” note by wiring the correct fastapi-users backend (e.g., cookie/JWT) and leaving a clear extension point for your chosen SSO provider if needed. You’ll receive runnable code, database models/migrations, and a short README showing setup and integration steps. I hope this helps. Ruslan D

⚠️ If you’re not happy, you don’t pay ⚠️ Hello, I can confidently offer this guarantee based on my extensive experience in developing secure authentication systems. Utilizing the Fastapi-users library, I propose a login/logout and user management system integrated seamlessly into your existing web application. For authentication, we will implement Basic Auth with a focus on Single Sign-On (SSO) for user login. All account creation and management will be handled exclusively by the admin, eliminating the need for user registration or password reset functionalities. In a previous project, I architected a similar system using Python, FastApi, and Postgres/SQL Alchemy, ensuring robust security and smooth integration. Moving forward, I would like to clarify a crucial detail: What specific user attributes should the admin be able to manage? Best regards, Piyush Gupta Senior Web Developer | Python Expert

@billybryan98

Hello, I hope you are doing well. I’m a backend developer with years of experience in Python and API design. I specialize in secure authentication for web apps and have deep hands-on work with FastAPI, PostgreSQL, and SQLAlchemy. I’ll deliver a clean, admin-controlled login system with a landing page that slots into your existing app using FastAPI-Users. Previously I built admin-managed user provisioning, login/logout, and SSO-based sign-in with OAuth2/OIDC, all without self-registration or password reset. The solution includes a clear separation of concerns and an easy integration path for you. I can deliver a ready-to-run example that matches your stack and governance requirements, with minimal changes needed for integration. Expect a concise, tested module within four days, with guarantees it will work as described. Best regards, Billy Bryan

@Techroj

Dear Client, Greetings!! I have gone through the project description, and found that all of the mentioned requirements fall over my expertise, as I have hands-on experience on python, AI/ML, Data Science, software building, etc.I can build a clean FastAPI + PostgreSQL auth system using fastapi-users with admin-managed accounts only, no public signup or password reset. I’ll implement SSO properly and include a working login landing page that drops into your existing app. One question: which SSO provider are you using like Google, Azure AD, Okta, Keycloak or should I select and wire the best option for you? I have been coding on Machine Learning and Data Science with python from past 7 years. I have the experience of working with 4 giant tech companies, including freelancing on upwork, fiverr and freelancer. Hope to hear from you soon!!. Regards, Rojan

@pablosilva91

Hi, I can build this authentication system for you efficiently. I specialize in Python/FastAPI and have implemented fastapi-users in multiple production environments. My approach for your project: • Backend: Setup fastapi-users with PostgreSQL/SQLAlchemy. • Security: Customize the logic to strictly forbid public sign-ups (Admin-only creation). • UI: deliver a responsive Login Landing Page integrated with the API. • SSO: Implement the OAuth2 transport for your preferred provider (Google, Azure, etc.). I noticed the listing mentions both Basic Auth and SSO. I can support both flows depending on your exact use case. I have the environment ready and can start right now. Best, PDS

@danylop55

Hey there, You mentioned Basic Auth and also SSO. Which one is the real target for V1: username+password login (no signup), or SSO (Google/Microsoft/Okta)? After login, do you want cookie session (browser app) or JWT token (API-first), and should the login page live inside FastAPI or be embedded into your existing frontend? I can deliver a clean working example using FastAPI + Postgres + SQLAlchemy + fastapi-users with: User model + migrations (Alembic) Login/logout endpoints (fastapi-users backend) Simple login landing page (server-rendered HTML) Admin-only user management: create users, disable/enable, list users, set roles No public registration and no password reset flows Clear module structure so you can drop it into an existing app Deliverables: runnable repo/example, env config, and a short integration guide showing where to plug routes, auth dependency, and admin guards. Hope to discuss more on chat. Best, Danylo.
