For those that do Azure presentations / screen recordings you know that you often find yourself scrubbing out your sensitive and personal information such as subscription keys, email addresses, keys and connection strings. What if you could have this magically done for you?
Well let me introduce to you a handy Chrome extension called Azure Mask that will mask GUIDs (such as Subscription IDs), email addresses, keys, and connection strings with a blur. The intention of the extension is to make it easier to do screen recordings without revealing sensitive, personal, account information that may show up on screen.
NOTE: This extension will only run and apply against Azure portal URLs.
- Blurs GUIDs (such as Subscription IDs)
- Blurs your account email
- Hides the "Report a Bug" button (if found)
- Toggle the mask on/off and store this state
- Apply the mask (if enabled) after Document Object Model (DOM) mutations
