Question:102436

It is not posible as the Token will expire in some time

I know the one time password will expire after the counting time.When you scan the QR code, it is just like a account and added to the list in Google Authenticator. The new added one will keep generating one time password vildation. I am asking is it possible to use that new generated passord, but not rescan new QR code and add new authenticator for genereating one time password.

But once you scan the QR Code you added the new account in google authenticator. The added account will keep generate OTP, but the sample can only use the first code. After a while, the code refresh, the check Dim isValid As Boolean = totp.VerifyTotp(txtOTP.Text.Trim(), timeStepMatched, Nothing) can't get the lateset code for check. I have to refreh and scan the new QR Code for adding another account in gogogle authenticator. How can I just use the same account and keep getting the latest code?
