A digital ID is like an electronic driver’s license or passport that proves your identity. A digital ID usually contains your name and email address, the name of the organization that issued it, a serial number, and an expiration date. Digital IDs are used for certificate security and digital signatures.
Digital IDs contain two keys: the public key locks, or encrypts data; the private key unlocks, or decrypts that data. When you sign PDFs, you use the private key to apply your digital signature. The public key is in a certificate that you distribute to others. For example, you can send the certificate to those who want to validate your signature or identity. Store your digital ID in a safe place, because it contains your private key that others can use to decrypt your information.
Digital IDs include a private key that you safeguard and a public key (certificate) that you share.
You don’t need a digital ID for most of the work you do in PDFs. For example, you don’t need a digital ID to create PDFs, comment on them, and edit them. You need a digital ID to sign a document or encrypt PDFs through a certificate.
Self-signed digital IDs can be adequate for personal use or small-to-medium businesses. Their use should be limited to parties that have established mutual trust.
Most business transactions require a digital ID from a trusted third-party provider, called a certificate authority. Because the certificate authority is responsible for verifying your identity to others, choose one that is trusted by major companies doing business on the Internet. The Adobe website gives the names of Adobe security partners that offer digital IDs and other security solutions. See Adobe Approved Trust List members.
Unfortunately, you cannot recover or reset the password if you’ve forgotten it. If you created the ID yourself, you can create a new one with the same information that you used for the ID. If you got the ID from a certificate authority, contact the authority for help.
Sensitive transactions between businesses generally require an ID from a certificate authority rather than a self-signed one.
