◇ Could this help me?
Yes, with one part to skip. The five findings are accurate and are the standard weak points in a generated auth screen, so treat them as a real checklist. Skip the closing instruction to paste a video link and let an assistant implement all of it unattended: authentication changes need to be applied and reviewed one at a time, because a broken authorization check fails silently and looks fine. This is a general practice.
Audit the authentication in this codebase against five specific weaknesses and report each one before changing anything: session tokens held in local storage rather than an httpOnly cookie, authorization or admin checks performed on the client instead of the server, absence of a second factor or one-time-password flow, missing rate limiting on the login and password reset endpoints, and missing password rules or breach checks at signup. Then fix them one at a time, smallest change first, and show me the diff for each before moving to the next.
