Title: MtGox mistakes YubiKey with OTP (resolved)
Post by: zby on April 14, 2013, 01:00:14 PM
When I try to withdraw anything (bitcoins via codes or define a bank transfer beneficiary) the forms ask for a YubiKey or OTP - I use YubiKey so I touch it and it sends a code into the form - but then I always get an "Invalid OTP" error.  Has anyone encountered this?  And yes - I  just sent a help request to MtGox - but I'd like to know if I am the only one with this problem - it looks like something pretty fundamental for all YubiKey users.

Try to hold the yubikey button for a few seconds instead of simply touching it.

Thanks!  This worked.  I am surprised - because for logging in I use the quick touch and I get in.

There used to be a text asking for a long press (>3s IIRC) when you use your Yubikey for withdrawals.

For clarification:

Yubikey has TWO built in keys, the "short press" and the "long press" key.

So by pressing and holding for more than 2-3s it actually sends a different key

The MT.Gox security app has set one key (short) to login, and the other (long) for withdrawal.
