How to Sign PDFs with a BIRD ID Digital Certificate on iPad
Question details
The user needs to sign a document using a cloud-based BIRD ID digital certificate but cannot find the required signing option in the mobile application.
- Product
- Adobe Acrobat Reader
- Device & OS
- iPadOS 15.6.1
- Scenario
- Attempting to digitally sign a PDF document using a cloud-based BIRD ID certificate on a mobile tablet device.
- Observed behavior
- The specific option to sign documents using a cloud-based digital certificate is completely unavailable in the iPad version of the application.
Ensure you have access to a desktop or laptop computer running Windows or macOS, as mobile apps currently have technical limitations regarding specific cloud-based digital certificates.
Sign the Document using Adobe Acrobat on Desktop
Since the iPad version of Adobe Acrobat Reader does not support cloud-based digital certificates like BIRD ID, you must use the desktop version of the application on a computer.
Mobile versions of PDF readers often lack the advanced cryptographic framework required to integrate external or cloud-based digital certificates. The desktop version of Adobe Acrobat fully supports advanced certificate-based signatures, including BIRD ID.
Save the PDF document from your iPad to a cloud storage service (such as iCloud Drive, Google Drive, or OneDrive) or email it to yourself so it can be accessed on a desktop computer.
Launch the desktop version of Adobe Acrobat or Acrobat Reader on your computer and open the transferred PDF document.
Click on the 'Tools' tab at the top of the window, scroll down to the 'Forms & Signatures' section, and select 'Certificates'.
Click 'Digitally Sign' in the top toolbar, click and drag to draw a signature box on the document, and then select your configured BIRD ID cloud-based digital certificate from the prompt to finalize the signature.
Sign and Edit PDFs Seamlessly with WPS Office
If you frequently work with PDFs across different devices, WPS Office provides a comprehensive suite of powerful PDF tools. You can easily insert electronic signatures, edit text, and manage your documents safely on Windows, Mac, iOS, and Android without heavy performance costs.
- 1. Download WPS Office: Install WPS Office on your preferred device (PC, Mac, or iPad) directly from the official website or the respective App Store.
- 2. Open Your PDF: Launch WPS Office and open the PDF document you need to view or sign.
- 3. Use the Signature Tool: Navigate to the 'Fill & Sign' or 'Insert' tab on the top ribbon, and click 'Sign' to create or import your electronic signature.
- 4. Apply and Save: Place the signature precisely where you need it on the page, adjust its size, and save the updated file securely.
Frequently Asked Questions
Why can't I use digital certificates to sign PDFs on my iPad?
Mobile operating systems like iPadOS use strict security sandboxing that limits third-party apps from accessing external or cloud-based cryptographic certificates. As a result, advanced digital signing features are primarily reserved for desktop versions of PDF readers.
Are electronic signatures the same as digital certificates?
No. An electronic signature is a digital representation of your handwritten signature or a typed name used to express consent. A digital certificate (like BIRD ID) relies on underlying cryptographic security to legally verify your identity and ensure the document hasn't been tampered with after signing.
Can I use the BIRD ID certificate on an Android tablet instead?
Currently, advanced cloud-based digital certificate signing is predominantly supported only on desktop operating systems (Windows and macOS). Android devices face similar technical and security restrictions to iPads regarding third-party certificate integration.
How do I easily move files between my iPad and desktop computer?
The most seamless method is to save your PDF to a cloud storage app installed on your iPad, such as iCloud Drive, Google Drive, or Dropbox. You can then log into the same cloud account on your computer, download the PDF, sign it, and upload it back.
