An email certificate is used to sign email messages and Office documents. The signature provides assurance about the sender and the contents of the file.
An email certificate can be used to send encrypted email messages which can only be read by the intended recipient. Both the sender and the recipient will need their own certificates to allow for email encryption. Signing and encryption is only possible using email software that supports S/MIME.
An email certificate can also be used as a client certificate to allow for secure login to online applications and services. In that case, the certificate replaces the traditional password or is used as another step in the login process. This is known as two-factor authentication. For added security, it is also possible to store the certificate on a PKI token.
