I need help finishing two small but connected items. First, I want a straightforward way to keep a daftar nama (name list). The names do not need the overhead of Excel or a full-blown database; a simple, well-formatted plain-text file is enough. I should be able to add a new entry quickly, see the existing list, and keep everything neatly organised in that single document. Second, I also need a lightweight sistem login so only authorised users can reach the list page and make changes. A basic username-password flow is fine; it just has to be clean, secure, and easy to drop into an existing project folder. Deliverables • Code and instructions for the login module • Script or small app that reads, displays, and updates the name list in the text file • Brief README so I can install, test, and tweak both parts on my own machine Keep the solution simple, clearly commented, and ready to run without extra licences or paid services.
