Have you ever needed to limit access to specific Excel sheets based on the user? Maybe you’re sharing a dashboard across teams, managing sensitive financial data, or simply want to prevent unauthorized changes to critical sheets. That was exactly the challenge I faced—until I built a secure Excel login system using VBA (Visual Basic for Applications).
Let me walk you through how I created it, what it does, and how you can implement the same solution to protect your Excel files with ease.
The Problem: Too Many Eyes on Too Much Data
I needed a way to control who sees what in a workbook. Giving full access to everyone wasn’t an option, but managing different versions of the same file for different users? That was a nightmare.
So, I decided to build a centralized user access system in Excel, where each person logs in with their name and password, and only sees the sheets they’re allowed to access.
The Solution: Building an Excel Login System with VBA
When you open the file, a custom login form immediately pops up. It’s clean, visual, and user-friendly. Instead of typing a name (and possibly making a typo), users select their name from a dropdown. Then, they enter their password.
If the password is incorrect, they get a polite message: “Wrong password.”
If the credentials match, they’re greeted with “Password OK,” and their specific sheets appear like magic.
Behind the scenes, the system is checking a “Users” sheet that includes:
- The username
- The password
- A matrix of sheet access with “X” marks indicating permissions
Each sheet name is listed in the first row, and each user has Xs under the sheets they’re allowed to view. The VBA code loops through this data to determine which sheets to unhide.
What’s powerful here is the use of “Very Hidden” in Excel VBA—a feature that makes it impossible for users to unhide a sheet unless they access the VBA editor. This is far more secure than simply hiding a sheet.
Under the Hood: How the VBA Code Works
Here’s a breakdown of what the code does:
- When the file opens, the VBA script hides all sheets, except for a central “Main” sheet.
- It then triggers the login form using
UserForm.Show. - The login form uses a
ComboBoxto list usernames dynamically from the Users sheet. - After submitting, the form checks the entered password against the correct one using a simple
VLOOKUP. - If successful, the code looks up which sheets the user can access and unhides only those sheets.
- Everything else stays locked down using the xlSheetVeryHidden property.
This way, each user gets a customized view of the workbook without needing multiple versions of the file.
Why This Approach Works
This system is:
- 🔐 Secure – With Very Hidden sheets and a login gate, your data is well protected.
- 🔄 Dynamic – You can easily add new users or sheets without changing the VBA code.
- 🛠️ Simple to maintain – Everything is centralized in one place: your Users sheet.
- 📊 Professional – Ideal for internal tools, dashboards, or any workbook shared with multiple roles.
Whether you’re managing inventory, sales, or HR data, this VBA user access control system in Excel will make your life a whole lot easier.
