Odd that it would still copy even though the clipboard failed. Otherwise this 
would normally be because another app had locked the clipboard for writing and 
WinAuth wasn't able to access it.

Of course this could be WinAuth from a bug. Restarting WinAuth should tell you. 
Does it still happen? How about rebooting?

Haven't seen the issue since the last restart.  Could have been an issue with 
the upgrade.  I used the clickonce installer.  i'll let you know if it happens 
again but so far so good.

Just happened again.  I canceled the password prompt at startup, waited a few 
hours before having to open the application.  Right click and copy produced the 
same error.

Latest version, now i'm having to hit copy, twice.  getting the error both 
times, but the code will only copy to clipboard correctly after the second 
copy.  It's pretty strange.

I can't explain why twice works. Do you have any clipboard monitoring 
software..and scanned for malware recently? Which AV do you use?

I've uploaded a diagnostic build to try and work out what's going on. Can you 
download this one:

https://winauth.com/downloads/3.x/WinAuth-3.1.7.18-DEBUG.zip

It doesn't have any changes except some logging information around the 
clipboard code, but nonetheless, please make a backup of your current 
authenticators.

If you run it and do a copy, and there is an error - another app has the 
clipboard locked for example - then it'll write some details to a winauth.log 
file. This file is in \users\<username>\AppData\Roaming\WinAuth, or in the same 
folder as the winauth.exe if you are in portable mode.

If you get the error, click Continue, and then can you send me the file.

Fresh format of Windows 8.1 with all updates, I don't have malware and use 
McAfeeASAP.com for virus protection.  Here's the error:

Requested Clipboard operation did not succeed.
   at System.Windows.Forms.Clipboard.SetDataObject(Object data, Boolean copy, Int32 retryTimes, Int32 retryDelay)
   at WinAuth.WinAuthAuthenticator.CopyCodeToClipboard(Form form, String code, Boolean showError)

From my research on this, it seems that this is and has been an issue with the 
clipboard API for some time. I've come across other instances where it 
literally needed to be done twice to work, or reports an error even though it 
worked.

I'll probably put together a new version that just doesn't report an error. 
Since that is likely a fringe case, where another app has actually locked your 
clipboard, it seems that ignoring is no worse than reporting it.

Do you almost always find it copies the first time despite an error appearing?

I wonder if there is a way to tell what is locking the clipboard?  It almost 
always copies the first time, I've recently noticed.  Not giving me an error at 
all today.  Nothing changed as far as I'm aware.

Before the copy is done, it checks to see if the clipboard is locked. If it 
was, you would get a different error message with the name of the 
Window/process that had the lock.

However, from the diagnostics you sent before, it's passing that test - no lock 
- but getting the error when it tries to put the data on the clipboard - as if 
there were a lock.

This was reported in Windows moons ago, and they even changed the API to let 
you specify the number of times to retry internally. Suggests that there is an 
underlying bug...and still not fixed apparently.

I guess the only thing that might help narrow it down is to remember what you 
last copied/cut/pasted before trying WinAuth. Or, before you do the WinAuth 
copy, do a test copy/paste in notepad or something.

Do you have more than one authenticator, and do any have "copy on new code" 
set? (by right clicking).

Just "copy code", don't use copy on new code.
