Supabase Auth Session Not Persisting Across Page Reloads
After authenticating with Supabase, the user session disappears when the page is refreshed. Users are logged out unexpectedly, and the authentication state is not being maintained across browser sessions.
This typically happens because the auth session data is stored in memory only, rather than being persisted to localStorage or sessionStorage. When the page reloads, the in-memory state is lost.
Common Causes
- Missing localStorage persistence in Supabase client initialization
- Incorrect session storage configuration in createClient()
- localStorage disabled in browser or private browsing mode
- Auth state listener not properly initialized before component mount
- Session token expired without refresh token handling
How to Fix It
Initialize Supabase client with proper storage configuration:
const supabase = createClient(URL, KEY, {
auth: {
storage: localStorage,
autoRefreshToken: true,
persistSession: true
}
})Add auth state listener on app mount to restore session from localStorage.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

Why is my user logged out after refresh?
Check if persistSession is enabled and localStorage is available. Add an auth state listener on app mount to restore the session.
How do I check if session is stored?
Open DevTools > Application > Local Storage and look for 'sb-' prefixed keys containing auth tokens.
