This extension allows you to set up a two-factor authentication using SMS for admin and frontend customers.
Navigate to "System/Green Flying Panda/Two-Factor Authentication" to enable this feature.
After performing the login operation, customers will be required to enter the confirmation code to continue browsing the store.
If the customer foes not have any cellphone defined, he will be asked to set up a new one.
You can force the customers to use two-factor authentication or give them the option.
Customers will see in their account, when editing the profile, a field to change their phone number or to, if enable, enable/disable two-factor authentication.
