Hi,

I stupidly changed my (admin) password and forgot to click 'save' in my password manager, so now I can't log back in to TOS 6.0.
I tried the 'forgot password' option but this ask me to send a verification code, which I don't receive by email (tried several times and waited for an hour).

Is there any way to log back in without loosing my data?
It's a F4-423 and I have 2 disks of 2TB in there, with 1 data pool and a volume.

I was up to my neck in the process copying back data from my PC to the NAS.
Hope anyone knows how to get back in or reset without loosing any data.

Thanks for the help,
:Dennis.

If you have not saved the password, it should still be your original password.
The inability to receive emails may be due to network issues, system abnormalities, or blockage. Try restarting the NAS to see if you can log in with the original password?

Resetting TOS6 generally does not affect your data.
If you have installed the system on HDD, please refer to this:

If you have installed the system on M.2 SSD, please refer to this:

Please note that if prompted with 'Delete/Format' during the reset process, stop the operation, otherwise data will be lost.

No I mean I haven't saved the password into my password manager.
So i DID change the password into TOS6 but I did NOT save it into my manger, hence I don't have the right password.. ':|
