Comodo Personal Authentication Certificate

Enable email signing & encryption, document signing and two-factor authentication

Comodo Personal Authentication Certificates offer myriad benefits by allowing you to digitally sign your emails and documents, encrypt your emails and even add two-factor authentication to your login pages. CPACs typically come with a 2048-bit RSA signature key and are universally trusted by OSs, Servers, Mobile Devices and other platforms. Make sure your customers and partners can verify the authenticity and creator of any documents or emails you send with a Comodo Personal Authentication Certificate.

Digitally Signs Emails

Your CPAC applies your digital signature to every email you send. When your email reaches its intended recipient, the signature will help them verify the sender's identity and that the message hasn't been altered.

Encrypts Emails

Thanks to the end-to-end encryption enabled by the certificate, your emails are safe from being intercepted, read, or altered.

Digitally Signs Documents

Similar to how it works with emails, your Pro and Enterprise CPAC will add your digital signature to any document you sign. This lets anyone who reads the document verify the identity of who made it and confirm the document hasn’t been changed since signing. If you need to sign PDF documents, we recommend our Adobe Approved document signing certificate.

Adds Two-Factor Authentication

After a Pro or Enterprise Comodo Personal Authentication Certificate is installed on your computer, your login page will request it every time a user attempts to log in to their account. This all takes place behind the scenes so there are no disruptions.

Trust

Assurance & Authentication

Nothing is more important than trust when it comes to the world of online business. Without it, you're not going to sell, convert-whatever goal you're trying to accomplish. Comodo Personal Authentication Certificates help you to build that trust by ensuring the integrity of your email and documents and assuring your users about your identity. Don't give your customers and partners any reason not to trust you. Purchase a CPAC today and start applying your digital signature.
