How To Password Protect Excel

Key Takeaway:

  • Creating a password for an Excel document adds an extra layer of security to sensitive information, allowing access only to those with the password. It is important to choose a strong password that is easy to remember but difficult for others to guess.

  • Additional security measures can be taken to further protect Excel documents, such as encrypting files with a Certificate or Password or using Digital Signatures to ensure the authenticity and integrity of the document. It is important to evaluate the level of security needed for the specific document and take all necessary precautions to protect it from unauthorized access.

Protecting your confidential Excel data is essential. Do you need to secure your spreadsheets and restrict unauthorized access? This article provides you with a step-by-step guide on how to password protect your Excel documents.

Creating a Password

To set up a protective barrier for your Excel spreadsheets, you may opt to lock them with a passcode.

To do this, follow these three steps:

  1. Open the Excel worksheet you want to secure and navigate to the “File” tab.
  2. Select “Protect Workbook” and then click on “Encrypt with Password”.
  3. Input your desired combination of letters, numbers or symbols in the pop-up box and validate it by entering it a second time. Click on the “Ok” button to confirm.

It is important to note that setting passwords for workbooks only limits unauthorized users from opening files and viewing data. They cannot restrict anyone from modifying or deleting the spreadsheet content.

Remember that setting a strong password is crucial to protect confidential information and sensitive data from potential hackers.

Back in 2015, major banks and financial institutions were targeted and robbed by a group of cybercriminals who stole hundreds of millions of dollars using Microsoft Office software vulnerabilities. Such mind-boggling incidents emphasize the need for robust password protection to ensure maximum security of sensitive documents like spreadsheets.

Removing a Password

To get access to your protected Excel files, you need to discover a way to bypass the password. Unlocking an encrypted worksheet is what you’d call it.

Removing a Password involves following these 6 simple steps:

  1. Open the file that should not be protected.
  2. Head over to the File tab and click on Info > Protect Workbook or Protect Sheet.
  3. Now, select Encrypt with Password option from the drop-down menu and click OK.
  4. Deselect the “Allow changes by more than one user at the same time…” checkbox if it is selected for better cautionary measures.
  5. You will be asked for a password, but instead of entering it, just leave it blank and hit OK.
  6. Resave your existing workbook/worksheets without giving any Password protection this time around.

Additionally, even though removing a password may seem pretty straightforward, keep in mind that once you remove it, anyone can view your document’s content. So please ensure that it makes sense when sharing important files.

Microsoft Office has been receiving trillions of reports and criticisms since its inception. However, Microsoft confronted numerous lawsuits between them providing new options and improvements until they finally added Password protection as one of their advanced features.

You can never be too paranoid when it comes to protecting sensitive information, so let’s add some extra layers of security.

Encrypting Excel Files

To encrypt Excel files, follow these 5 steps:

  1. Open the Excel file you want to encrypt.
  2. Click on ‘File’ in the top left corner.
  3. Select ‘Info’ then click on ‘Protect Workbook’ dropdown menu.
  4. Choose ‘Encrypt with Password’
  5. Type your desired password and confirm it, then click ‘OK.’ Your Excel Workbook is encrypted now.

It’s worth noting that encrypting an Excel file will affect its performance slightly, so avoid excessive use of encryption to prevent encumbered use.

Password protection is a simple yet effective way of guarding confidential information. It should be noted that longer and more complex passwords are harder for cybercriminals to break. Always remember to store passwords safely, allowing only authorized personnel access.

In fact, according to Microsoft, “Passwords with eight or more characters which contain both upper- and lower-case characters and at least one number or symbol are secure.”

Protecting Sensitive Data with Digital Signatures

Protecting crucial and sensitive information demands modern solutions. Digital signatures offer a secure method of validating the authenticity of documents, verifying their integrity, and protecting them against tampering. By using crypto techniques, digital signatures can ensure data confidentiality and non-repudiation. This cryptographic technology is highly effective in protecting sensitive data.

Digital signatures can be easily integrated into Excel spreadsheets to protect confidential information from unauthorized access or modification. They provide an additional layer of security that verifies the source and content of the spreadsheet, ensuring it has not been altered since signing. Using digital signatures to password-protect Excel spreadsheets provides data integrity guarantees for sharing information with partners or colleagues via email.

Incorporating digital signature protection into your workplace procedures can help safeguard against cybercrime in today’s increasingly sophisticated threat landscape. Digital signature technologies are widely used by banks, insurance companies, government bodies across various jurisdictions worldwide.

According to a report by MarketsandMarkets Research Private Ltd., the global market size for digital signatures was $1,013 million in 2020 and is expected to grow at a CAGR of 31.0% from 2021 to reach $5,750 million by 2026.
