Easily password protect a PDF on an iPhone.
To secure personal information in any PDF, you can password protect it from anywhere using a few simple steps from Adobe Acrobat online services.
There are numerous reasons to protect the contents of a PDF. Perhaps you have a legal document, financial contract, or rental lease to share. These kinds of documents contain sensitive information that should be viewed only by certain people. But when you are away from your desk and working on your iPhone, you may still need to protect and send that information quickly.
You don’t need any special apps or software to encrypt a PDF — you just need to add password protection, and you can do it quickly using an iPhone.
Acrobat online makes it easy to password protect any PDF, creating a secure, encrypted file.
Use these steps to password protect a PDF on an iPhone.
- Be sure you know the location of your file, whether it’s stored on your iPhone or on a cloud-based service.
- Click the blue “Select a file” button to navigate to the file and upload it.
- A screen will appear displaying your file and a field for you to type a password. Create a strong and unique password, and then retype it in the second box to confirm.
- Click “Set password.”
- After your new password is set, you can download the file.
- You can also sign in to Adobe or another service, such as Apple or Google, to share it with others over email or via a link.
Your file is now secure and can only be opened by others if you provide them with the password. Communicate the correct password in a separate correspondence, ideally on a different channel for an added level of security.
Examples of PDF files you should password protect.
Other kinds of PDFs you may want to password protect include:
- Financial reports
- Strategic business plans
- Tax forms
- Anything you send via email
- Contracts or legal agreements
The information in these forms is not something you want your competitors or anyone else to access. The Acrobat online tool encrypts your file for additional security, so you can share passwords carefully.
