It’s not necessary to have a QNAP account (ID) to use a QNAP NAS online and get updates. 
Hi, i would like to dm you my Mac adress for getting the cloud Key.
I have the same issue basicly.
I cannot acces my nas interface anymore because my password is not able to reset.
I tried the reset pin for 3 seconds untill it beeps. It goes to another IP adress in my network but the old login still works somehow. However, then the issue is again that i cant get in without my 2fa code.
Any advise on this? I created this account to be able to reply here so its not linked to my qnap interface either.
You can also open a ticket, not sure I understand what issue you are facing (2FA should be disabled after a reset)
Hi, I lost the admin password of my TS-233 , no stricker with the Cloud-Key , how I cand send you the macaddress via PM ? Thank You
You can also pop both of your disks out (while the NAS is off of course) and use Qfinder to read your cloudkey

After that coldswap (!!) your disks back into the NAS and …voila
Ok thank you! I’ll try
But if I send you the mac address , may i receive the cloud key, the Qnap is not physically available at the moment.
I have adjusted your permissions, you should be able to send me a PM now.
