How to Sign PDF Documents with Digital Certificates on Mobile
Question details
The user needs to sign a PDF document using a digital certificate on a mobile app.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to apply a highly secure digital certificate signature to a PDF document while using a mobile phone or tablet.
- Observed behavior
- The standard Adobe Acrobat Reader mobile app does not provide the digital certificate signing tool, preventing users from completing the certificate-based signature process.
Ensure that your digital certificate is valid, properly issued by a trusted Certificate Authority, and accessible on your mobile device.
Use Acrobat Sign for Mobile to Apply Digital Certificates
Since the standard Adobe mobile app lacks certificate tools, you must use the dedicated Acrobat Sign app designed for advanced electronic signatures and workflow management.
The standard Adobe Acrobat mobile application focuses on basic viewing, commenting, and simple electronic signatures. For cryptographic digital signatures that use a digital certificate to verify identity, Adobe provides these capabilities through their enterprise-level Acrobat Sign platform.
Open the Apple App Store or Google Play Store on your mobile device, search for 'Acrobat Sign', and install the application.
Launch the Acrobat Sign app and log in using your Adobe ID or the enterprise credentials provided by your organization.
Navigate to the 'Waiting for Me' section or import the PDF document that requires your digital signature.
Tap on the signature field within the document. Choose the digital signature option and follow the on-screen prompts to authenticate and apply your digital certificate to the PDF.
Sign and Secure PDF Documents with WPS Office
WPS Office offers a comprehensive suite of PDF tools for mobile and desktop, allowing you to easily add electronic signatures, annotate, and manage your documents securely on the go.
- 1. Install WPS Office: Download and install the WPS Office app from your device's app store.
- 2. Open your PDF: Launch the app and open the PDF document you need to sign.
- 3. Access the Signature Tool: Tap on 'Tools' at the bottom of the screen, select the 'PDF Edit' or 'Annotation' tab, and tap 'Signature'.
- 4. Create and place your signature: Draw your signature, save it, and tap anywhere on the document to place it securely.
Frequently Asked Questions
Why doesn't the standard Adobe app support digital certificates on mobile?
The standard Adobe Acrobat Reader mobile app is built for basic document viewing and light annotation. High-security features like cryptographic digital certificate signing are managed through Adobe's specialized Acrobat Sign app to ensure enterprise-level compliance.
What is the difference between an electronic signature and a digital certificate?
An electronic signature is a digital image or tracing of your handwritten signature used to indicate agreement. A digital certificate, however, is a highly secure, encrypted file issued by a Certificate Authority (CA) that cryptographically binds your identity to the document, proving it has not been altered.
Can I sign PDFs with a digital certificate on my desktop computer?
Yes, desktop versions of PDF editors like Adobe Acrobat Pro and WPS Office for PC have built-in support for importing and applying digital certificates (such as .pfx or .p12 files) directly without needing a separate app.
How do I install a digital certificate on my mobile phone?
You can typically install a digital certificate by downloading the certificate file to your device. Tapping the file will usually prompt your mobile operating system (iOS or Android) to import it into its secure credential storage, making it accessible to supported apps.
