SigningHub also allows you to use OTP via SMS as secondary authentication method in conjunction with any of the pre-configured authentication method above. This will make you feel more secure by going through two-factor authentication at the login time.

The availability of OTP security feature as two-factor authentication is subject to your subscribed service plan and login authentication settings. If you are willing to use this provision, please contact your Enterprise Admin to enable it in your Role under "Authentication".
