Solving the mystery: What is the passcode for VNeID? Can the passcode of VNeID be changed?

Frequently asked questions

The technique involves using a VBA (Visual Basic for Applications) code to lock and protect your Excel files with a password. This adds an extra layer of security to your sensitive data and ensures that only authorized individuals can access and modify the file.

The VBA code utilizes the Workbook_Open event, which is triggered when the Excel file is opened. Within this event, the code checks if a specific password has been provided. If the correct password is supplied, the file is fully accessible. However, if the wrong password is entered or no password is provided, the file remains locked and only displays a message instructing the user to enter the correct password.

This technique enhances the security of your Excel files by requiring a password to access the content. It prevents unauthorized modifications, protects sensitive data, and ensures that only those with the correct password can interact with the file. This is especially useful for office workers handling confidential information or collaborating on projects where controlled access is necessary.

Implementing this technique is straightforward. You can copy and paste the provided VBA code into the Visual Basic Editor in Excel. Customize the password by changing the ‘password’ variable within the code. Save the file as a macro-enabled workbook, and your Excel file will now be locked and require a password to unlock.

It is crucial to remember the password you set, as there is no recovery mechanism built into the code. If you forget the password, you will be unable to unlock the file. Therefore, it is recommended to choose a secure yet memorable password or store it in a password manager. To change the password, simply reopen the Visual Basic Editor, modify the ‘password’ variable, and resave the file.
