Existing user security applies when switching users using barcodes. For example, your user accounts are password-protected, users will still be prompted to enter these passwords when switching profiles using barcodes.
You can also choose to allow user switching with barcodes without requiring a password. To do this, follow the steps below:
1. Navigate to Setup > General in the sidebar.
2. From the User switching security drop-down, select Don't require a password to switch users when switching with a barcode.
3. Once selected, click Save.
Quick user switching will always require a password when switching to an account with higher privileges. If a user has not logged in for the day, they will have to enter their password once to allow switching without a password afterward.
