Can a document author password protect something after its already downloaded?

If I download a document from a website and am not required to enter a password to open it after I’ve downloaded it, is it possible for the author to add password protection to the downloaded document later? For example, let’s say I am a member of a paid website that allows its members to download documents. Let’s say I’ve downloaded some stuff and was not required to enter a password at the time. If I cancel my membership can they somehow change my downloaded copy in my computer and add password protection? Meaning if I cancel my membership I could possibly lose access to the stuff I’ve already downloaded?

Awesome. I looked up online how to check to see if they used DRM and they don't for any of their documents. Thank you so much!

My adobe/ PDF documents are password protected. How can I remove the password?

@My adobe/ PDF documents are password protected. How can I remove the password?

Hello,
two answers I found in my library about removing or finding unknown password:
Removing: "Not with any Adobe products, and other products are not discussed on these forums..."
Open a file: "The only way to open a password protected file is to know the password (there's no way to get around that). Hopefully you know who created the PDF and can get the password from them."

PASSWORD PROTECTING A PAGE WITH A NICE BOX DESIGNED INTO YOUR PAGE
FINALLY, I'VE FOUND AN ANSWER TO PASSWORDING A PAGE OR SECTION WITH ADOBE MUSE WITH GREAT SIMPLICITY AND ALLOWING YOU TO 'DESIGN' THE PASSWORD BOX INTO YOUR PAGE!!!
Even better is that you don't HAVE to have username AND password (although you could if you wanted to), so just a simple PASSWORD box and enter button DESIGNED BY YOU WITHIN YOUR PAGE, rather than nasty popups etc. Importantly, the password itself is NOT within the source code of your page either!!
The solution is at Jotform.com. I believe you can do this with a FREE ACCOUNT, although it's SUCH a great service for Musers that I paid for a proper account.
Before you do this, create a page on your site saying "Wrong Password. Please go away" or something to that effect. You'll need it for when they enter the wrong password.
So, in Jotform, you just create a new form and:
1. Drag on a password box (it's in the power tools section)
2. Select it and go to Conditions
3. Go to Change Thank You URL after submission
4. Enter: If [name of your password box] field EQUALS TO [enter your password]
5. In the "Then redirect to" box, enter the URL of your protected page and click save
6. In the resulting box click "ADD A NEW CONDITION" and do the SAME as stets 3 to 5 but this time say NOT EQUALS TO" with your same password and in the "Then redirect to" box, enter the URL of your WRONG PASSWORD page and click save
7. Embed the button on your page and you're done!!!
If you want to mess about with the EXACT alignment of a right aligned button and text box, you can go to Preferences and in the box which allows you to add your own custom CSS, enter the following code and mess about with the values until it's perfect for you:
.form-buttons-wrapper { padding-top:3px !important; }#id_2 {margin-left: -50px !important;}
Here's an example, built in Muse: www.hileytv.com/about.html
I hope this helps my fellow Musers!

Some apps allow you to do this with documents, photos, and videos but it is not possible to do with apps. Your best and only solution is to use the phone passcode.

When combining files, conversion keeps failing with red notice that the document if password protected. What does that mean and what do I do?

When combining files, conversion keeps failing with a red notice that the document is password protected. I was combining all pdf files and had just been successful with some of the same content under a different file name. What is wrong and how do I correct it?

Hey SUSANO,
I am sorry but you cannot combine files if they are password protected.
You can check the same under 'File > Properties> Security

When I try to convert a pdf to Word, it says the document is password protected. What should I do?

When I try to convert a pdf to Word, it says the document is password protected and the Word option is gray.

Probably, give up. But
* if you HAVE the password you can remove it with Acrobat Pro
* you can ask the document's creator for an unprotected file
Sometimes passwords are added automatically and not known, for example some banks do this; there is no solution.

Can a file be password protected using Adobe Acrobat XI Standard? No one seems to have answered this question in the trending questions.

I just purchased Adobe Acrobat because it was recommended to password protect files.
However, when I checked out the Tools > Protection > Encrypt> "Encrypt with Password" is greyed out.

The OS version is Windows 7.

Thanks.

Yes, it can. Use File > Properties, and click the Security tab. Click Change, and set what you need. When the file is saved, the security is set.
BE SURE TO KEEP THE ORIGINAL FILE TOO.

Is it possible to lock a layer within a document and password protect that specific layer?

Is it possible to lock a layer within a document and password protect that specific layer?

As stated, no way to do exactly what you want, but an option might be to turn OFF Visibility for that Layer, if you do not want it seen, and then Flatten, and do a Save_As.
If you do want that Layer seen, but not able to be edited, then Flatten, with Visibility ON, and Save_As.
The question is, do you want the recipient to see that Layer, or not?
Next, Do they need to be able to edit all other Layers, but just not that one?
Last, what type of Layer is it?
Good luck,
Hunt

How can I make a password protected encrypted sparse image?

How can I make a password protected encrypted sparse image?
Doing what worked in 2006 does not produce password protection even though I have typed one in and re-entered it as requested. Clicking on the Disk image opens it without asking for the password. I am stumped. Many thanks.

Yeah, nobody does. They should put up a custom password save box when you make an encrypted disk image that explains what will happen if you store the password in the keychain. In the current "how-to" article, they mention it, though: How to create a password-protected (encrypted) disk image - Apple Support

How can my end user password-protect a document that has been digitally signed?

Hello,
I have seen some threads that indirectly address parts of this question, but am still left unsure about whether this process can be done - and if it can, I could use your help in understanding it - thank you.
Two of our end users use digital signatures (certificate-based) in Acrobat 9 Pro to sign documents attesting the accuracy & calibration status of lab equipment for use in a legal environment. These end users are concerned that their documents could be altered or edited, and asked me if password protection can also be applied to their documents that need to be digitally signed.
Thank you in advance for your advice.

Do you apply "Open" password or "Permissions" password or both? If you apply "Permissions" password (with or without the "Open" password) make sure that "Changes Allowed" include Filling in form fields and signing existing signature fields" or "Commenting, filling in form fields and signing existing signature fields". If permissions do not allow you to sign, you cannot sign.
Be aware of the alert that Acrobat pops up when you apply "Permissions" password that all Adobe products respect permissions that you set but that 3rd-party PDF Viewers may not (and many do not).
That is exactly what I was missing! I apply only "Permissions" password, but had the "Changes Allowed" drop-down set incorrectly - it was set to "None." After changing that setting to allow "Filling in form fields and signing existing signature fields," the end user was able to digitally sign the document, her desired goal.
Thank you so much.

I can not seem to password protect a pages document

I created a document with pages. I thought I had password protected it. However document is not requiring password to open.
I used password protect from the file menu of the document. I even changed the password but nothing sticks. What am I doing wrong?

When you choose File > Set (or Change) Password… if you always want a password challenge, even on your own machine, then do not check Remember this password in my keychain from the drop-down Pages password sheet.
If you did, you may have to remove the password, and subsequently re-add it following the above guideline.
