I'd like to ask you if there are any possibilities of a two-factor authentication with authentication code sent to email. I've found TFA module which can send an SMS, and according to their documentation, also email:
The TFA code can be sent out over mobile phone SMS (recommended) or via email.
but I haven't found any settings for email, it seems they just provide "API to customize the communication chanel". I've also found Rules module, which could be maybe used combined with other module.
Are there any other possibilites how to do the two-factor authentication with email?
