How do I password protect a PDF document on a MacBook Air?

I am trying to password my PDF documents on a macbook. I don't understand why the help options are not assisting me. Can someone help me please?

If that doesn't work it may be that you don't have Acrobat. This is not the free Adobe Reader but something fancier.

  • How do I password-protect a PDF document that doesn't let me change the security settings?

    I want to password-protect my PDF document (so when I email it, it can only be opened/read by intended recipients as it contains confidential/sensitive information) but when I go into document security, I'm unable to change the Security Method (which is currently set to 'No Security' - not by me).  There's a 'show details' icon but it's grey so I can't click on it.  What can I do to protect this document from being opened by non-intended recipients?

    Ah, yes, I'm using Adobe Reader!  That makes sense.  Thanks so much for your reply.  At the moment, I scan Word documents into my computer and they're automatically converted to PDFs.  If I had Adobe Acrobat on my computer, and scanned in documents, would they open in Reader automatically or could I open them in Acrobat and therefore add password protection?

    On the File menu, click Save As.
    On the Tools menu, click General Options.
    Do either or both of the following:
    If you want users to enter a password before they can view the workbook, type a password in the Password to open box, and then click OK.
    If you want users to enter a password before they can save changes to the workbook, type a password in the Password to modify box.
    NOTE   Unlike passwords you specify in the Password to open box, passwords you specify in the Password to modify box are not encrypted. These passwords are only meant to give specific users permission to modify workbook data. For optimal password security, it's best to assign both passwords. An encrypted password to access the workbook, and one to provide specific users with permission to modify its content. IMPORTANT   Use strong passwords that combine uppercase and lowercase letters, numbers, and symbols. Weak passwords don't mix these elements. Strong password: Y6dh!et5. Weak password: House27. Use a strong password that you can remember so that you don't have to write it down.
    If you want to use a different encryption type, click Advanced, click the type you want in the Choose an encryption type list, and then click OK.
    If needed, specify the number of characters you want in the Choose a key length box.
    NOTE   Document property encryption is enabled by default for most encryption types and providers. It prevents unauthorized users from viewing summary and custom file properties (such as the author or any custom file information) in theProperties dialog box. When users right-click the password-protected file, and then click Properties, information won't be available on the Summary tab and Customtab. Authorized users, however, can open the file and view all file properties (Filemenu, Properties command). To disable document property encryption, clear theEncrypt document properties check box.
    Click OK.
    When prompted, retype your passwords to confirm them.
    Click Save.
    If prompted, click Yes to replace the existing workbook.
    NOTE   You can also secure a workbook with a password on the Security tab of the Options dialog box (Tools menu, Options command).

  • How do i password protect a pages document?

    i have a document that i created in pages.  it is a worksheet for brides (we are wedding photographers).  i use to have the document set up so when i email the document to a client, they can read the questions/timeline but cannot edit my text.  i have cells in tables that they can answer in.  the cells were grey in color.  the way i did this was by maybe putting a password on the document (which left the area grey for them to respond in).  but i cannot remeber how i did this.  i'm wondering if anyone knows what i'm talking about and/or how to do it.

    Password protection prevents a document from being opened without the password.
    Locking an object (such as a text box or table) prevents the object of its contents from being altered without first unlocking the object. No password protection is available for this, though, so the recipient could easily unlock the object and change its content.
    At least one of Adobe's PDF applications offers the features you want—non-editable base document with fields that can be filled by the user, then saved and the file returned.

  • Adobe PDF pack- Annual: How to add password protection to my documents now?

    I purchased the paid PDF product in order to add password protection to existing PDFs or docx, but I still don't see an option for how to add it. I tried creating Docx and then creating PDF- but never got the option to add a password or security of any kind.
    Please assist

    Hi rachel.stewart,
    In order to password protect your files, you need Adobe Acrobat. Please refer to the links mentioned below:

  • How do I password protect a pdf file - getting error messages?

    I'm trying to protect a pdf file (i.e. a tax return printed to PDF) with password to open and password to modify. However I'm getting an error message in a pop up window saying..."The file may be read-only, or another user may have it open. Please save document with a different name, or in a different folder." I'm using WIN 8.1. and I'm using Adobe Acrobat Pro XI (student / teacher version). This is a standalone PC so I can't imaging someone else is using this file. Also I've tried renaming and saving to a different folder (from the folder the original file is saved). I've also looked at properties of the PDF file and its not tagged as read only. Please advise if I'm missing something. Thanks for your help.

    Thanks for responding...I'm getting the same message that I got at first..."The file may be read-only, or another user may have it open. Please save document with a different name, or in a different folder."
    The next day I emailed the file to my work PC and encrypted it with no problems. I have WIN 7 and am using Acrobat 8.0 there. So the problem seems to be with my new PC here at home (i.e. WIN 8.1 and Acrobat XI). Frustrating. I'm betting its some obscure setting in WIN or Acrobat, that is way over my head. Please let me know if you have any ideas. Thanks again.

  • Password Protection of PDF file generated thru SAP

    Hi,
    I have written a program to send payslip through email . This mail sends the payslip as a PDF attachment.
    I want to password protect that PDF document, so that it asks for a password before being opened by the employee.
    Your suggestions will be highly appreciated.
    Sanchit

    Hi sanchit,
    1. The payslip passes thru SCOT
       settings,
       which in turn generates the PDF
       and sends mail.
    2. SCOT does not provide any such facility,
       for password protection.
    3. I don't think the password
       concept can be done in a normal fashion !
    regards,

  • How to password protect a numbers document

    I'm trying to figure out how to password protect a numbers document.
    My intention is to load this document onto a website, but only want authorized persons with the correct password to be able to access.
    Any ideas??
    Thanks

    I am using Numbers 08
    And the Numbers User Guide, supplied with iWork '08, make no mention of password protection, which was introduced in Numbers '09.
    Looks like the best option is Wayne's second suggestion—open via File > Print > PDF > Open in Preview, then Save the resulting PDF document with encryption turned on.
    An alternate, if you want the recipients to receive a copy of the Numbers '08 file, and to be able to edit that file, you could enclose it in a secure disk image file.
    The basic procedure is to:
    Use Disk Utility to create a new, blank, sparse disk image, assign a password and save.
    Double-click the .dmg file (and enter the password when requested) to mount the disk image on your desktop, then Save a copy of your file to the (open) disk image.
    When done, eject the image, and upload the (encrypted) .dmg file to the website.
    Detailed instructions may be found in Disk Utility's Help files.
    Launch DU (found in the Utilities folder in Applications), click the Help menu and choose Disk Utility help.
    Go to the index, scroll to and click Security, then click a title similar to "Protecting confidential documents in a secure disk image." (a search on 'confidential' should also take you to a list containing that title.)
    My version of DU is old enough that sparse images hadn't been introduced, or I'd post a copy of the article here.

  • How to password protect a PDF to not allow more than 3 attempts

    I am looking for a way to password prtotect a PDF document which will alllow the user only 3 attempts. If the user does not enter the password correctly, the document must be locked out and should expire.
    So basically, the user should not be allowed to try more than 3 times to open the document.
    Any help in this regard would be highly appreciated.
    Thanks....

    You will not be able to achieve the functionality that you are looking for with "Password" based encryption\protection. 
    There is no way to monitor\audit the number of attempts to open a password protected PDF

    Select File > Document Security from the menu
    Got to the u201CSecurity Optionsu201D drop-down and select u201CAcrobat Standard Securityu201D
    Find the box labelled u201CPassword required to open documentu201D and place a check mark against it.
    Edit or type the password
    You can also add a password requirement for changing permissions or password.To add a a required password check the box against u201Crequired password to change permissions or passwordu201D and enter the password. However note that this password must be different from the one that you entered for securing or password protecting the PDF file.
    If you want your PDF document to be password accessible to users with previous versions of Acrobat Reader (versions earlier than 5.0), do not change the 40-bit encryption setting. However if your users or audience will be using version 5 or later versions of the Reader (or the full Acrobat program) then you may use 128-bit encryption.
