Staying secure is a journey with multiple steps



What is MFA (and why should you care)?
In a nutshell, multi-factor authentication (MFA) means using something else besides your password to gain access to your account. There are many ways to do this – some, such as texting a one-time PIN to your phone are less secure than others, such as using a $25 Google Titan security key or the free Authy/Twilio smartphone app. The idea is that if your password is compromised (such as a reused one that has been already leaked in another breach), your account is still secure because you have this additional secret to gain access.
Is MFA slightly inconvenient and does it require some additional effort to log in? Typically, yes. However, when weighing this inconvenience against the consequences of having your identity or funds stolen because of poor security hygiene, it becomes clear what’s at stake.  
Twitter was recently hacked, and it appeared to be a social engineering ploy on one of its employees. The hackers were able to reset account passwords through their administrative tools, regardless of whether MFA was enabled or not.
After hearing the news, I realized that I still have enabled SMS on Twitter and also on PayPal. It’s important to note that this method is less secure than others. With that in mind, allow me to give you instructions on adding the best kind of MFA to your accounts.
