TS431K 2-step authentication not working and need to turn it off

Tried to turn on 2-step authentication but QS Authenticator codes are not working. I tried to turn off this function and I am unable to log in to change the requirement for 2-step. I tried resetting the unit 2 times without success. I have NO access as admin or as user. Need some assistance please!

Be sure to follow the steps to perform a 3 second reset as noted here to clear 2FA.

The default password will be reset and depends on your firmware version

If this fails, you should contact QNAP support

Thanks… I have been through these steps without success. The link to the Admin default password is also a loop that goes nowhere… I will file a note with support. Thanks much!

Interesting. I have no issues with the link or information. Browser cache or popup bloacker?
