If Proof accepts Individual’s Certificate Application, Proof will provide the Individual Digital Certificate to Individual, as an individual, subject to the terms, conditions, and restrictions stated in the Agreement. Proof has no obligation to provide the Individual Digital Certificate to Individual. Proof will tell Individual the length of time that the Individual Digital Certificate is valid.

Proof will issue and manage Individual Digital Certificates in accordance with the applicable terms of the Proof Certificate Policy available at www.proof.com/legal/certificate-policy and the Certification Practice Statement available at www.proof.com/legal/certification-practice-statement.
3. Issuance. If verification of the Individual is completed to Proof’s satisfaction, Proof will issue and deliver the Individual Digital Certificate using any reasonable means of delivery. Proof may change which root or intermediate certificate is used to issue Individual Digital Certificates at any time and without notice. If Proof is unable to confirm the Individual’s identity, Proof may refuse to approve the Certificate Application or refuse to issue an Individual Digital Certificate without liability to any person or entity.
4. Defective Individual Digital Certificate.
