Hey @OLLI_S,
Thanks for writing in.
I would like to share that Enpass can auto copy the TOTP, just after filling the login details and you can paste that right in there
Thanks!
Please follow these simple steps on your Windows 7 PC:
Download Enpass from this link.
Now open Enpass --> And Restore the data from same OneDrive account which you are using on your Home PC.
If I misunderstood the problem please explain little more so that I can help you better.
Thanks!
