How to enable OTP SMS Two-Factor Authentication for eSigner Code or Document Cloud Signing

SSL Support Team
This is a guide on how enroll an SSL.com document signing or code signing certificate to use the One Time Password (OTP,) Short Message Service (SMS,) two-factor authentication method to digitally sign an electronic document or sign code.

An OTP is required when applying a digital signature for all individual validation document signing certificates and organization validation document signing certificates. For organization document signing certificates, an eSealing conversion may be requested enabling automated signing without an OTP (users who want their organization doc signing certificates to be converted to eSealing should contact support@ssl.com). 

For code signing automation methods visit our CI/CD integration guide.
