Build Real Web App Authentication with Sessions and Protected Routes

About this workflow

A step-by-step flow to implement real signup, login, logout, session persistence, password reset, validation, and protected routes with visible UI states and mobile responsiveness.

What happens when you run it

Best for

• •Recurring tasks you currently copy-paste between tools.
• •When a single prompt isn't enough — you need a chain where output(n) feeds prompt(n+1).
• •Fork and adapt if your inputs differ materially from the author's use case.
