      Authy was hacked. If you use this particular security tool, the main concern is an increased risk of SMS phishing or phone number theft because attackers now know what cell phone number is associated with Authy-protected accounts.


      Recommended mitigations:
      1) Update to latest version of Authy app.
      2) Contact your carrier and ensure your phone number is locked to prevent unauthorized number transfers.

      Your phone is the weakest link in your digital security
