So I've been using Electrum wallet for over a year now without any issues but now am encountering an "invalid otp" whenever I try to send my bitcoins to another wallet. I figured out that the wallet I sent my bitcoins was not the wallet I usually use (I have the seed words and google authenticator for this wallet). The coins got sent a default wallet in which I don't have the seed words nor is it connected to google authenticator. I have a large some of coins in this wallet, and I can't seem to send them anywhere. Is there anything I can do to send these coins to the wallet I usually use? Or have I completely lost these coins?

OTP stands for one time password, the 6 digit code you get from google authenticator. Are you sure you entered it correctly and that you're using the right code? You won't be able to send any coins without the right otp...

So I only set the google authenticator up for 2 wallets, and the wallet my bitcoins are on is not one that I have an authenticator for. I have no idea how those coins got into a wallet that I don't use in the first place.

Why don't you have the seed words for your wallet? Didn't you back them up when you created the wallet, or did you create the wallet by importing private keys?

I can open the wallet with the coins, but is there a way to setup the google authenticator after the fact now. I have the master public keys for this wallet since I can open it.

Someone else with a similar "invalid otp" problem to yours started a thread about it here.

Someone from trustedcoin advised him to contact them here about Google Authenticator problems.

If you have the seed you can restore full control and bypass google authenticator by creating a new wallet from the seed. The instructions are here.
