Archisteamfarm: ASF 2FA Invalid length for a Base-64 char array or string while accepting trades

[kinosang]

I fully read and understood contributing guidelines of ASF available above, especially the point that GITHUB IS NOT TECHNICAL SUPPORT AND IT'S THE PLACE ONLY FOR ASF BUGS AND SUGGESTIONS.

I admit that THIS IS NOT A QUESTION OR TECHNICAL ISSUE caused by my lazyness of reading ASF wiki. I strongly believe that the bug I'm reporting here affects majority of ASF users, and the enhancement I'm suggesting could benefit ASF in long-run.

If my issue is not meeting contributing guidelines specified above, especially if it's a question or technical issue, please close my issue immediately - I won't complain.

Now that you read and understood the notice, pick appropriate bug/suggestion template and fill it with your issue.

If my issue is not meeting contributing guidelines specified above, especially if it's a question or technical issue, please close my issue immediately - I won't complain.

Reason for closing: technical issue is not ASF bug. You supplied invalid ASF 2FA credentials.

[kinosang]

I've tried to import the same maFile into WinAuth, it works well. But it does not work with ASF 2FA

[JustArchi]

Confirmations in WinAuth won't work either. And !2fa will work for you too.

[kinosang]

I see the identity_secret in my maFile is a string of 17-digits number, is it in wrong format?

[JustArchi]

ASF GitHub is not technical support. If you want to receive one then move onto proper channel.
