Two factor authentication (also known as 2FA) is a highly recommended security feature that adds an extra layer of protection to your tiny+ user account.
Enabling two factor authentication means that tiny+ will require a seven digit security code (in addition to your password) when you sign in to your account from a new browser, phone or tablet.
In order for two-step verification to work correctly, you'll need a mobile device capable of receiving SMS messages and running the Authy iOS or Android app.
