Hi Ton,
Thanks for posting your question!
MS Authenticator accounts can be backed up via iCloud on iOS devices and through the Cloud Backup option on Android devices. If your corporate device doesn’t have iCloud enabled, you won’t be able to transfer the accounts from your personal to your corporate device.
As a workaround, you can add your account on the corporate device through aka.ms/mysecurityinfo and then remove the account from your personal device.
