Salam Salah!

Congratulations on what you are doing with your CRM.

I suggest looking for unit testing as the functionalities and the maintainers' community are growing.
I also highly recommend delegating authentication and RBAC to third-party tools (Keykload, auth0, firebase, etc).

Lastly, I invite you to have a look at my library Jelban (or if there's similar/better): https://github.com/Fcmam5/jelban-js (context: https://github.com/Fcmam5/jelban-js/wiki)

If you want to prevent people from using temporary/fake email addresses to register (I'm guilty of registering with fake emails :) )

All the best,
