Protecting Your Excel File with Encryption

To prevent others from accessing data in your Excel files, protect your Excel file with a password:

1. Select File > Info.

2. Select the Protect Workbook box and choose Encrypt with Password.

3. Enter a password in the Password box, and then select OK.

4. Confirm the password in the Reenter Password box, and then select OK.

Warning:

• Neither Microsoft or La Salle's IT Department can retrieve forgotten passwords, so be sure that your password is especially memorable.

• There are no restrictions on the passwords you use with regards to length, characters or numbers, but passwords are case-sensitive.

• It’s not always secure to distribute password-protected files that contain sensitive information such as credit card numbers.

• Be cautious when sharing files or passwords with other users. You still run the risk of passwords falling into the hands of unintended users. Remember that locking a file with a password does not necessarily protect your file from malicious intent.
