We're pleased to announce that we have shipped a variety of new features that enhance account security and help us detect fraudulent accounts automatically.
Our dashboard will now use a wide array of signals to compute a score of how trustworthy a particular account operation is. Examples of these signals include where you're accessing our services from (your location, network, device, etc), where you've previously accessed our services, whether your IP or device is associated with other accounts, and many, many more. If, after looking at these signals, we determine that we'd like more assurance that you are actually you, we may prompt you for a code that we'll send via email.
We will continue to refine and enhance this system over time to ensure your dashboard's security.
