By Microsoft’s own admission, you should not assume that a file, workbook or worksheet is secure simply because it is password-protected. The same encryption standard applies across every tier. You may notice that there are differences of scale, not degree. Workbook-level encryption allows you to assign individual worksheets to individual team members, meaning that they can work on their designated sheets, but no others can.įinally, worksheet-level encryption limits the amount of functions team members can perform within a particular worksheet so that the data sets remain consistent. As discussed above, you can encrypt individual files for file-level so that only people you have shared the password with can access them. Within Excel, there are three types of encryption : file-level, workbook-level and worksheet-level. Your only option at that point would be to attempt retrieval using Virtual Basic for Applications, or VBA, the programming language of Excel.
#How to add password for excel file crack#
Assuming you would not want the same password for all your files, this situation could quickly become a headache for everyone involved, not to mention that the more times a password is entered, the more opportunities hackers have to crack it.įurther complicating matters is the fact that if you lose or forget a password, Excel has no mechanism that would allow you to recover it.
Once you set a password for a particular file in Excel, you or whoever else has access will be required to enter the password each time you want to view that file.
Password protection is already the weakest among security measures, and the more people you have to share it with, the more vulnerable it inherently becomes. This is especially true if you know the file has to be seen by multiple parties. You don’t want your password to be easy to guess, but you also don’t want it to be too complicated to remember. It is also possible to require a digital signature to access a file. This is the most basic security measure within the Excel framework.Īnother measure you can take at this level is to make the file read-only, meaning that unless someone has a second password, they cannot modify the file. From the “File” tab you select “Info,” followed by “Protect Workbook” and “Encrypt with Password.” You then enter your preferred password and confirm it by entering it a second time. Making an Excel file password-protected is a fairly straightforward process. This means you must control who gets to view that data and when.Įxcel offers some in-house security measures, and there are third-party extensions available as well, but are they adequate? Here we will explore those options and see how they stack up against virtual data rooms. Not only do Excel files often hold some of your most important and sensitive information, but that information is presented neatly in spreadsheet form, making it an easily exploitable asset for anyone with bad intentions. Microsoft Excel is the industry standard for organizing and laying out data sets.
