We want to let you know about a vulnerability that allowed someone to enter a phone number or email address into the log-in flow in the attempt to learn if that information was tied to an existing Twitter account, and if so, which specific account. We take our responsibility to protect your privacy very seriously and it is unfortunate that this happened. While there’s no action for you to take specific to this issue, we want to share more about what happened, the steps we’ve taken, and some best practices for keeping your account secure.
