Hello ,
Since,last week I have been developing multi - factor authentication via mobile phone(by sending one time password to the user) prototype. The OTP prototype works using user's email address ,when it is complete I will work on sms integration in zotonic and thus, instead of sending an email to the user it will send an otp to the user's mobile phone.
I have committed all my code on github, Here is the
link .
All my changes are in mod_authentication ,when everything is working I will shift it to a separate module and will link this new module to mod_authentication. So that the user gets a chance to activate/ deactivate multi-factor authentication via mobile phone( for secured login by extra tier of security ) in the site built using zotonic.
Regards,
Anant
