You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. However, you can't prevent saving copies of a PDF. The copies have the same restrictions as the original PDF. Two types of passwords are available:
If the PDF is secured with both types of passwords, it can be opened with either password. However, only the permissions password allows the user to change the restricted features. Because of the added security, setting both types of passwords is often beneficial.
Type and retype your password. Your password must be at least six characters long. The password strength is displayed next to your password to indicate whether the chosen password is weak, medium, strong, or best.
Select Require a password to open the document, then type the password in the corresponding field. Your password must be at least six characters long. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
Choose Editing, and then type and retype your password. Your password must be at least six characters long. The password strength is displayed next to your password to indicate whether the chosen password is weak, medium, or strong.
Type the password in the corresponding field. Your password must be at least six characters long. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
Select Require a Password to Open the Document, then type the password in the corresponding field. For each keystroke, the password strength meter evaluates your password and indicates the password strength.
If you're worried about somebody gaining access to your information, you can add an extra layer of protection to those documents by password protecting those PDFs with Adobe Acrobat. Unfortunately, this feature is not free and is only available on the paid version of Acrobat Pro.
If you lose the passwords, Elcomsoft sells a PDF Password Recovery program. I used it on a PDF-centric job to see if it could crack our security and (unfortunately for us at the time) it did so easily.
I had some password protected PDFs that were not required to be of limited use by me in any way. It would not matter if they were opened by anyone who managed to get into my machine (it would be too late by then to try protecting the PDFs).
I got tired of locating the text file and keeping it together with the PDF copy.
Finally, I ended up renaming the PDF file with the password attached at the end.
Now, whenever I had the PDF handy, so was the password.
End of unwanted-password-recollection story.
put the passwords into a text file, displayed out of the way on the screen and cut and paste as required. As well as a simple text tool, any software that can provide this functionality could be used, e.g. a clipboard manager (like Glipper under Gnome) or a keyboard macro. Alternatively use a keyboard shortcut to deliver the password when required.
where possible, get PDFs from sources that do not require a password to open them for reading. Lobby other suppliers to change their policy. For example, just two from the many suppliers that do not password protect PDFs for reading:
b. Packt Publishing changed their policy and now provide PDFs that do not need a password to read. Indeed, if you bought password protected PDFs from them in the past you can download a copy of the unlocked version for free. Again, the files have pages marked with customer details.
Commercial providers can support business cases that do not require a password for reading files. PDFs that do not require a password to open for reading simplify access, allow file contents to be searched and allow file browsers to display the front-cover icon.
I developed the following AutoHotkey script to automate the entry of passwords into a variety of PDF readers. You pass it the full path to the PDF and the password, and it opens the PDF with your default reader and attempts to enter the password for you.
I compile this script and set up shortcuts to it and the document / password. For example, if I have a PDF called C:\bleh\my.pdf with a password of abcd, I create the shortcut "C:\someapps\pdf_passwd.exe" "C:\bleh\my.pdf" abcd.
It has undergone many incarnations over the years for Sumatra PDF and Adobe Reader 9/10 on Windows XP and 7. Sumatra PDF now has a built-in "remember password" option, but when I initially developed this it did not. If you are not tied to Adobe Reader, I would highly recommend Sumatra PDF over Adobe Reader for basic PDFs.
PDF Unlocker is a simple and useful application that can remove all kinds of restrictions on PDF files. It works by removing passwords that restrict access in two areas. One is for passwords that restrict some functions such as printing copying and pasting. The second is any password that might prevent you from accessing or opening a PDF file.
I have one PDF that I would like to share with multiple people, but temporarily protected. Is it possible to create a one time password? Example: The first person to open the PDF would have to have the password to open it. After the password was entered and the PDF was opened, the password would then be automatically erased.
This is only a temporary password, not a one time open password. Once you've downloaded the PDF, opened and entered in the correct password, the password is removed. You can then open the pdf without having to put in a password anytime.
The whole point is that not everyone understands Acrobat (my parents or people who rarely use computers). If they could just be sent a secure PDF and have a password, they could then open the PDF with the password and not have to worry about remembering it, writing it down, saving it,.... I know it's "easy" to go in and remove the password protection, but it would take 30 minutes to explain how to some people.
I downloaded a PDF from my bank. I can open the PDF just fine. But if I try to edit the PDF - add or remove a page, for example - it demands a Permissions Password. I've tried every password I have to no avail.
I have Adobe Acrobat X Pro and have never encountered this issue before. The bank swears they did not set a password on their end. Some documents from their site are "secured" with this Permission Password, and others are not.
And to confirm: many banks do this. The bank employees are not technicians and know nothing about it. There is no way they can give you the password even if you manage to explain why you want to edit your statements. (Indeed, it is to stop editing of the statements that they do this).
I just came across this problem today. I work for an attorney and a client emailed me a bunch of bank statements that I need to combine, process and prepare for production to the other attorney. Wow! This is a really stupid thing - Permission password? Phooey! I can't merge into one pdf, can't insert, can't rotate. Nothing! So, I tried to print so that I could manually scan (I figured it would be easier) and it only let me print the first page. Pretty irritating! So, finally, I decided to Save As to JPEG. It created individual jpg pages. Then, I selected all of the jpg files I wanted and printed to pdf. It created one file with which I can now work. The file is huge - the pages with the copies of deposit slips and checks made large files, but I could reduce the size a little bit. But, oh well, it was a solution and took a lot less time than printing and scanning. Part of my processing is adding document numbers in a footer. I do not appreciate this permission password bit, especially since there is nobody on the planet, it seems, that knows the password, but I guess I can anticipate more of this craziness.
I would like to make it known that the reason for my original comment was to help other poor souls who come across the same problem. I had an issue and went looking on the internet to see if anyone was able to remove or get access to the permission password for their documents. I have found that many people have not found good solutions, some none, except for one person who has a Mac, instead of a PC. I found a solution that, although not optimal, works.
I mean no disrespect, but your comment makes me think that you didn't really read my comments very well. You see, I never said there was a problem with Adobe, Acrobat or PDF file format. It sounds like your trying to rightfully shift blame, when I put no "blame" on Adobe, etc. at all. Obviously, it is the creator of the file, ie. the bank, financial institution, etc. I totally get that and I actually got that the first time around from someone else's comment that was made a year ago, even before I read your initial comment on the matter. Actually, I understood that prior to even searching the internet for a solution as I have a decent understanding of how Acrobat works. But, obviously, there is next to zero chance that I, or any other regular banking customer, is going to be able to make actual contact with the person who secured the document to get the permission password. One would think that maybe they could let the customer pick the password or have it be some form of a social security number or something, just maybe. However, I have no issues with Adobe in this matter. I like Adobe. Well, I actually love Adobe Acrobat. I wish I had time to take classes to learn how to efficiently and expertly use Adobe's different products. Alas, I haven't the time for that, maybe when I retire. But, nonetheless, the situation is really bothersome when one is not able to do what one has always done, which happens to be part of one's job. It is part of my job to compile and organize clients' documents and put document numbers on them and sometimes redact information prior to giving them to opposing counsel and the Court. The Court prefers digital pdf far more than scanned pdf and they demand that certain information be redacted or covered up prior to filing with the Court. Adobe Acrobat is AWESOME for this. I used to hand Bates stamp document numbers on each page. Let me tell you...The options in the the header/footer window in Acrobat Professional are AWESOME! Redacting social security numbers and birth dates and account numbers in Acrobat is a breeze. Having to hand stamp and hand redact just costs the client more money, which I would prefer not to do, and more time than I would like to spend.
