Aah, the emphasis is ‘offline’.
So if you you are ‘online’, it’s obligatory to await the 6 digit code from AxCrypt’s servers, BUT…
If we switch-off wifi (so offline), the program recognizes this and allows decryption WITHOUT having to enter a 6 digit code.
Very clever! and worth remembering.
I’m very reassured by this, and have just recovered all of my test data successfully without using AxCrypt’s servers, or even the internet. Great!
