TS14 - Spike: Research Authentication Strategies in Express.js

[RamirezJM]

As a Backend Developer
I need to research and evaluate authentication strategies and libraries (such as Passport.js or native JWT implementation) for Express.js
So that we can implement a secure, scalable, and best-practice session/token management system for SecondChance.

Details and Assumptions

• This is a Technical Debt / Spike issue focused on knowledge gathering and architectural decision-making, rather than delivering user-facing features.
• The outcome should compare different authentication methods considering the constraints of our MongoDB database.
• A brief summary or technical decision log should be documented or linked in this issue upon completion.

Acceptance Criteria

Given the security requirements for the SecondChance user service
When the authentication research and evaluation are completed
Then a clear technical recommendation for implementation (including libraries and token lifecycle) must be documented and approved
