I am trying to get password entered by user from TKTokenPasswordAuthOperation. When system call beginAuthFor i am returning TKTokenPasswordAuthOperation. now i need password that user has entered. when i try to access password property in TKTokenPasswordAuthOperation class it is nil. How i can get that password.

I am working on Token extension on iOS. Apple documentation say if We throw error with error code "TKError.Code.authenticationNeeded.rawValue" will trigger user authentication. In my TKTokenSessionDelegate class in sign dataToSign function i am throwing this error but my extension is not showing authentication screen. Any Idea what i am missing.
