[USG FLEX] Google Authenticator (2FA) synchronization behavior on dual partitions

Zyxel_Luna

The current firmware version is [V5.43].

During the upgrade process, the Google Authenticator data on the currently running partition will be synced to the new running partition (the original standby partition).

If you revoke and re-register Google Authenticator on the running partition—causing the two partitions to become out of sync—do not worry. You can resolve this by performing another upgrade.

The upgrade process is as follows:

1. Upload the firmware upgrade file to the standby partition (P2).
2. After rebooting, the Google Authenticator data on the previously running partition (P1) will be synced to the standby partition (P2), which is now the active running partition.
