I'm developing my first admin panel and I have some significant security worries. The admin panel will be used to manage users, change their subscription statuses, and display analytics. It needs to be accessible from multiple IP addresses. Currently, I'm using Supabase, which has multi-factor authentication (MFA) in place. Only the designated admin user can access this panel with a strong password and MFA via an authentication app. I've ensured the page has a random name, avoiding obvious routes like '/admin.html'. I haven't used `localStorage` or `sessionStorage`, I'm not relying on any CDNs, and I have client-side rate limiting in place—I'm looking into server-side options as well. However, I'm wondering if there's anything essential I've missed. Is having a distinct admin page exposing me to more security risks? Should certain login emails have separate dashboards compared to regular users? Or is it better to manage everything using Supabase?

One thing to avoid is using JavaScript links that can't open in new tabs; instead, use standard `a` tags with `href`. It's a common mistake some developers make.
A couple of things to consider: make sure your admin authentication is separate from regular users at the database level, not just through UI differences. Even if someone discovers your random page name, they shouldn't get access if your permissions are set up correctly. I like your idea of having different dashboards based on email roles, that's a solid way to implement role-based access control on top of Supabase. Don't forget about audit logging to track changes—it's essential for keeping a paper trail if issues arise.
Make sure all validation happens server-side; client-side checks can easily be bypassed. Putting your admin panel on an obscure path won't keep it secure. Always validate and check permissions for every request, and ensure your inputs and outputs are strictly validated. Don't forget to keep your dependencies updated. If security is a top concern, consider IP whitelisting for your backend, although some people consider it overkill.
Your setup looks good but reconsider a few points. Random page names don’t provide real security; if someone gets hold of your auth, they can discover it through network requests. Also, prioritize server-side rate limiting over client-side, which can be easily bypassed. For the dashboard question, I recommend using role-based access with the same login process. It's easier to manage and keeps your system more secure. Be sure to include audit logging to track admin actions, and make sure your Supabase policies are strict—those are key for real security! Have you thought about session timeout policies for inactivity? That could help enhance security.
Thanks! I’ll focus on setting up server-side validation ASAP.
