- Secure attribute on every cookie
- HttpOnly on session cookies
- SameSite=Lax or Strict on session cookies
- No session identifier in URLs or localStorage
- Session rotation after login and logout invalidation
How to fix it

- 2Move tokens out of localStorage to HttpOnly cookies
Qwik context
Resumable framework that serialises state into the HTML payload.
