T-Mobile recently had a data breach which resulted in 47 million people’s data being leaked online. Much of that data was collected with user consent when they signed up for cellular phone service, but that’s not always the case in a data breach, as many companies collect data without users’ knowledge or express consent. And even if you have consented to your data being collected, if it isn’t stored securely or is held onto for longer than necessary, the risk of your data being leaked in a breach increases.
