Why you should password-protect PDF files?
If you work with sensitive documents, it is essential to secure PDF files. It ensures that only authorized individuals can access sensitive information, such as financial records, personal data, legal documents, or proprietary business information.
Password protection also helps prevent unauthorized changes to the document. Once the paper is protected, no one can change it without the correct password.
All added images, scans, and PDF signatures would remain untouched. This is especially important when sharing documents with multiple people.
How do you set a good password when protecting PDF files?
When protecting a PDF file, it is necessary to choose a strong password that is difficult for others to guess. It should be at least eight characters long. The password helps to ensure that only you have access to the file and its contents.
Without one, someone else could easily access it and may use the information for malicious purposes.
Here's a checklist
- Choose a passphrase. An effective password is usually a phrase or series of words, not just one word.
- Use a mix of characters. Include uppercase and lowercase letters, punctuation marks, and numbers in your passphrase to lock PDF.
- Avoid predictable patterns. Don't use common phrases or the same letters in consecutive order (e.g., "password123").
- Avoid personal information. Don't add easily guessable data like your name, address, or date of birth.
- Store passwords securely. Use a password manager to keep all passwords in an encrypted form.
- Change passwords regularly. Updating your passwords often can help keep them secure and reduce the risk of being hacked.
However, it can happen that you have come up with a very complex password and you have managed to forget it. In such a situation, you can always use the tool to remove the password from the PDF file.
