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.

Who Receives a Certificate?

• Client personnel within a company who are authorized to use ADP Internet payroll products

Important Security Considerations

It is important to protect your computer and keep its data secure. These recommendations can prevent the unauthorized use of ADP Internet payroll products from your computer:

• Keep your computer's operating system and browser up-to-date with the latest security patches and service releases.
• Use anti-virus software to protect your computer.
• Use a BIOS password when logging on.
• Keep your original or backup disk in a secure place, such as a locked cabinet. Only authorized users should have access to it.

Your company's help desk or support staff can help you to implement these recommendations. If you require assistance, contact your ADP regional service center representative.
