I will build a secure login and authentication system with django or flask


About this gig
Looking for a login system that actually protects your users, not just one that works?
I build authentication systems using Django or Flask, from simple login and signup flows to complete systems with role-based permissions, session security, and brute-force protection.
This is not surface-level work. Password hashing, environment variable protection, secure session management, and protection against common vulnerabilities such as CSRF and SQL Injection are applied because I understand why each one matters, not because a tutorial said so. This approach comes directly from building Vault, a password manager project handling encryption and secure session handling from the ground up.
What you get:
Secure password storage using industry standard hashing
Django or Flask, matched to your project needs
Role-based access control when needed
Clean, well documented code
Clear communication throughout the project
Message me before ordering if your project has specific requirements. I am happy to discuss scope before we start.

FAQ
Do you provide the source code?
Yes. Full source code is included in every package, with no restrictions on use after delivery.
I am not sure if I need Django or Flask. Can you help me decide?
Yes. Send me a message before ordering describing your project, and I will recommend the best option based on your needs.
Can you work on an existing project instead of building from scratch?
Yes, depending on the current state of the code. Send me details before ordering so I can confirm scope and timeline.
What information do you need from me to start?
A clear description of the features you need, any design references or branding materials, and access to hosting or database credentials if the project requires them.
What happens if I need changes after the revisions included in my package are used?
Additional revisions can be purchased as an extra, or included in a custom offer if the scope changes significantly.
Do you sign NDAs?
Yes, I am comfortable signing an NDA if required before starting the project.
