Remote Authorisation Signing (RAS)
Introduction
SigningHub provides Remote Authorised Signing (RAS) feature, to allow you to authorise a remote signature (done on server) using your registered mobile device(s), running any of the SigningHub native apps (i.e. Android or iOS). The device will have its user authentication built-in (touchID or PIN), so in a way you can also get two-factor authentication. The feature is available on those Android devices that support fingerprints verification, while in case of iOS devices, it can work with both touch ID or passcode verification. For RAS Signing configurations are required in the ADSS Server, SigningHub Admin, and SigningHub Web. Remote Authorisation Signing (RAS) supports the "Advanced Electronic Signature (AES)", "Qualified Electronic Signature (QES)", and "High Trust Advanced Signature (AATL)" levels of assurance. The availability of Remote Authorised Signing (RAS) feature is subject to your subscribed service plan and assigned role.
