How to Password Protect a File on Mac [Full Guide]
- Recently, Microsoft is making a change to its Microsoft Office branding. Microsoft Office is being renamed by Microsoft 365. After the official renaming, our article content will be updated accordingly.
There may be instances when you need an additional layer of security for the files stored on your Mac. Even though a password secures your computer, there may be times when someone else must use it. You may want to restrict their access to your files, such as budget spreadsheets and personal writing. Some of us may have to send papers to one another over an unreliable channel, like the internet.
Are you responsible for keeping private and sensitive information in Microsoft Word documents? If so, it is best for you to password-protect these files.
The ability to safeguard a folder on a Mac with a password will come in handy at some point. It means that you can store sensitive information such as your financial details or a secret work project without worrying that anyone who does not have a password will be able to access it. Adding password protection to your documents and folders will help secure them in all these scenarios. This article will concentrate on several approaches that may be of assistance to password protect a PDF Mac.
Using the built-in Disk Utility that comes with macOS, it is simple to lock a PDF or other files with a password. It generates a password-protected.dmg archive file using AES encryption, which requires a key to decrypt before it can be opened.
The following steps will show you how to secure folders using Disk Utility:
Step 1. Select "Applications > Utilities > Disk Utility" to launch the Disk Utility application.
Step 2. Navigate to the "file> New Image > Image" from the "Folder" option on the top menu bar.
Step 3. Go to the folder you wish to encrypt with a password and click the "Choose" button.
Step 4. Give your secured folder a name and choose a place to store it if you want. Open the "Encryption dropdown" menu, select, and click the "Save" button.
Step 5. When you are finished, click the "Choose" button after entering a password.
Step 6. You can also click the key symbol and let macOS generate a secure password for you automatically. When you are completed, click the Choose button once again.
Step 7. Click "Image Format > Read/Write". In the future, you can modify the contents of your protected folder by adding and removing items and clicking on the "Save" button.
Step 8. Ensure that Disk Utility has finished encrypting your folder before proceeding. When it's finished, you'll be left with a disk image that is password secured as well as the folder that was there before. You can delete the older folder if you no longer need its contents.
Step 9. On your Mac, to access the password-protected folder, just double-click the.dmg file to open it, and then enter your password when prompted to do so. If you provide the right password, the image of the drive will mount, and you will have access to its contents. This includes the ability to add or remove files and folders as needed.
When using the Preview program on a Mac, it takes around ten seconds to password protect Excel, PDF, Word, etc. However, those few seconds you spend might save you hours of effort and thousands of dollars if you secure that document now to avoid information theft in the future. It is possible to produce a PDF that is secured by a password using Preview but to do so, the document must first be saved in PDF format, and you will have fewer customization possibilities.
This is what you should do:
Step 1. Launch the Preview app and choose a file from the menu. Next, choose "Open", and go to an image or PDF file.
Step 2. Enter a new name for the PDF if you wish to produce a copy secured by a password while preserving the original's ability to remain unencrypted.
Step 3. After you have done any of the following, please be sure you click the "Permissions" button:
- Set a password to prevent unauthorized access to the PDF: Choose to ask for a password before opening the document. Please enter a password, then retype it to ensure it was entered correctly.
- Set permissions: To enable printing or updates to be made without entering the owner's password, choose the "checkbox" next to the action. If you want to require the owner to provide a password, deselect the "checkbox".
Step 4. In the Owner Password area, enter a password, then retype it to ensure it is correct. It might be the same as whatever password you generated in step 3, or it can be something completely different.
Step 5. Click the "Apply" button, then click the "Save" button.
Your BetterZip passwords can be safely stored in a vault managed by your password manager. BetterZip can automatically use the correct password whenever you open a password-protected archive by cycling through the list of possible choices.
To find out how to achieve this, please refer to the instructions below:
Step 1. Set a master password to protect the password manager's settings and passwords.
Step 2. Check this box to save successfully entered passwords automatically.
Step 3. Add a new password with "+" or "N". To delete a password, hit the "back" button. Password removal clears the cache. Edit passwords as text display one password per line in a text editor.
Step 4. Set when BetterZip should lock your vault. Leaving all checkboxes unchecked will leave your passwords accessible.
Step 5. Unlock the password manager to make changes.
Step 6. Change your master password. It encrypts BetterZip's password vault. While unlocked, the master password is saved in the macOS keychain.
Step 7. BetterZip may propose secure passwords when needed. To copy the suggested password, click "generate new passwords".
