If you use a third-party security method, you usually don’t need to share your certificate with others. Third-party
providers may validate identities using other methods, or these validation methods may be integrated with Reader.
See the documentation for the third-party provider.
When you receive a certificate from someone, their name is added to your list of trusted identities as a contact.
Contacts are usually associated with one or more certificates and can be edited, removed, or reassociated with
another certificate. If you trust a contact, you can set your trust settings to trust all digital signatures and certified
documents created with their certificate.
You can also import certificates from a certificate store, such as the Windows certificate store. A certificate store may
contain numerous certificates issued by different certification authorities.
