Can't login after password change

Hello!

I don't know why, I had to change my iCloud (Apple) password this morning. Did it on iMac, all fine.

On my MacBook Pro (OS 10.9.5), I'm asked to enter my password. All normal so far.

After I entered my new password, a verification code is sent on my iPhone, and I'm asked to type my password followed by the verification code...

The problem is that there is no place to write the dams code, no field, nothing. I'm stock there. Did it twice, same thing.

Thanks!
