Is it possible to open a password protected pdf on an iphone? Does not work as regular pdf using "Open In". When downloaded, the pdf prompts for the password. The "Open in" button displays for a second, but then disappears after typing in the password and it does not let you associate it with Adobe Acrobat after.
You simply need to type in the correct password of that PDF to open the PDF.
Make sure you know the password that is associated as the password of the PDF.
You simply need to launch the PDF and it would prompt you type the password and after typing in the correct password you would be able to view it .
