You may notice that if you are signed in to the Record app but leave the app not recording you will be prompted to re-enter your password. This prompt will show after 12 minutes. It is designed to ensure that another user doesn't accidentally record to the wrong account if the device has been left signed in.
The password prompt will only show if you are using the app with personal mode turned off.
For devices using personal mode, because these devices aren't shared between users there is a much lower chance of a user accidentally uploading to the wrong account.
If you have paired with another device to make a dual recording you will need to enter your password on both devices if they have personal mode turned off.
