Using a Digital Certificate
ADP Internet payroll products require users to present a digital certificate that is electronically signed by ADP, a user ID, and a password every time they log on. Requiring a digital certificate (something you have) and signing on with a user ID and password (something you know) provides a higher level of security than user ID and password alone.
Digital certificates use public and private key encryption, a technology developed about 20 years ago. ADP has implemented its own certificate authority for issuing digital certificates. A certificate authority is a trusted central administration that vouches for the identities of those to whom it issues certificates.
