Two factor authentication
The drumbeat of “secure your accounts; help your customers secure their accounts with you” advice has faded away a bit, probably because we’ve not had a major ESP account compromise hit the media in the past few months.
The costs – customer support, security, reputation, executive focus – of customer account compromises are still significant, anything you can easily do to mitigate that in advance is still a good idea.
If two factor authentication isn’t available as an option on your platform, talk to your developers about getting it on their roadmap. If it is an option, maybe use it as a hook to hang a promotion on?
Good idea, Freddie!
