So, someday this 12 months, the USA stopped implementing daylight financial savings time, in order that our time shouldn’t be adjusted by 1 hour twice a 12 months. I stay on the east coast and have an encrypted android machine that’s offline completely. I’ve put in the Google Authenticator app on this offline machine and it has been working flawlessly (offline) for 4 or 5 years now. This 12 months, I attempted to entry an trade that I’ve an account with, I enter my 2FA to log in and it retains telling me that I’ve the mistaken code. I’ve set the time accurately, the time zone, the date (I’ve had to do that earlier than to right the time on this offline machine, it’s persistently off by a couple of minutes per 12 months so it must be corrected infrequently) and nonetheless it tells me my code is mistaken. I went backwards and forwards with the trade and disabled my 2FA and locked withdrawals. This is the place issues get wierd…

I figured it was an issue with the trade till I attempted to log right into a 2nd trade the place I used to be having the identical difficulty. This tells me that it’s a downside with my 2FA… This is the place issues get extra bizarre…

I can now verify that none of my 2FA codes being generated are right on the offline machine. I deleted the 2FA for the primary trade and set it up once more with the offline machine, it nonetheless would not work… but when I export the 2FA to my common mobile phone (on-line), the code being generated works nice. I put in the most recent model of Google Authenticator onto my mobile phone, and used a USB follow switch the most recent model to my offline machine for set up. It nonetheless will not generate the correct code.

I do not know the place the difficulty lies… any assistance is appreciated. I actually don’t need my 2FA machine to ever be linked to the web.
