How to password protect documents

Password protection is invaluable for any company or organisation that sends, shares or stores documents, either internally, or with third parties.

No matter what size your business, the handling of sensitive information means that security needs to be a top priority.

Having password protection on your documents ensures that sensitive company or customer information is kept safe from prying eyes or being tampered with. Here, we teach you how to enable password locks for every type of file, including folders, PDFs, Excel files, zip files and Word documents.

 

How to password protect a folder

For Windows Vista, 7, 8 and 10 users, there isn’t an option to password protect files or folders. However, you can download programs and apps to do this. You can also use a similar alternative, which is encryption. Though the process is different to password protect, an encryption key will be used to access your locked files. This gives you the same level of security.

1. Choose the folder you want to encrypt

2. Right-click and select ‘Properties’

3. On the ‘General’ tab, click on ‘Advanced’
