Does WSO2 support SMSOTP and EmailOTP together? - wso2

Question

I am working on an application where I need to use multi-factor authentication using WSO2.
I have gone through the below mentioned links for configuring second factor using SMSOTP and Email OTP
https://docs.wso2.com/display/ISCONNECTORS/Configuring+Multi-factor+Authentication+using+SMSOTP
and
https://docs.wso2.com/display/IS530/Configuring+Email+OTP#ConfiguringEmailOTP-ConfiguringtheEmailOTPproviderStep2-ConfiguretheEmailOTPprovider.
After configuring both the above mentioned authenticators am getting the errorlog as follows:
INFO {org.wso2.carbon.identity.mgt.mail.DefaultEmailSendingModule} - User credentials configuration mail has been sent to smehta6991#gmail.com
ERROR {org.wso2.carbon.identity.application.authentication.framework.handler.step.impl.DefaultStepHandler} - Error while sending the HTTP request.org.wso2.carbon.identity.application.authentication.framework.exception.AuthenticationFailedException: Error while sending the HTTP request.

You can configure both authenticators in multi-step authentication(eg: SMSOTP in first step and EmailOTP in second step) or multi-option authentication. Here both authenticators will be available in a single authentication step and user has the option to select which authenticator to be used. You can follow the documentation in [1] for more information regarding this.
