What is a Sync Key and why do I need one?

When you set up a Sync account we generate a long string of numbers and letters that we call a Sync Key. The Sync Key is used to encrypt your data before it's sent to the Mozilla servers. Think of it as a key that locks your information in a vault that only you can open. Then you store this locked vault on the web server. This means that neither Mozilla nor anyone else can ever read your information without having your Sync Key to unlock it.

Where's all my data?

It's encrypted with your Sync Key and safely stored on the Mozilla servers. Because Sync uses advanced security measures your information is never vulnerable to online bad guys or companies that will sell your information.
