Why your barcode keeps changing
A new barcode every 30 seconds, against screenshots and recordings
Your barcode changes automatically every 30 seconds. Have the current barcode in the app scanned. The screen stays open for up to 3 minutes.
Expired codes are rejected. This limits reuse of old screenshots and recordings. A recent copy may still be within the valid time window, so checking the name and photo remains important.
Do I need internet?
You need internet to open the page. The next codes are then ready for this short session. Reopen the page when the barcode disappears. The clock device still needs a connection.
