AdWords Editor account security
Google is firmly committed to the privacy of our advertisers and users, and we make it a high priority to help ensure the security and confidentiality of the information you provide.
Your account information is encrypted and stored behind a firewall, and Google uses industry-standard SSL (secure socket layer) technology to protect every interaction you have with the AdWords system.
When you download AdWords Editor, Google assigns your copy of the software a unique identifier. We use this identifier to examine the software for suspicious account activity, such as unauthorized access.
When you're not downloading account data, posting edits, or checking for updates (on startup or every 25 hours of continuous use thereafter), AdWords Editor is offline.
