Signature Passwords
Signature Passwords: give phishers no chance
Signature passwords are 100% counterfeit proof.
No wonder they are most often used by banks.
Part of the transaction data is encrypted into the signature. Therefore if the signature changes, the transaction should change as well.
Furthermore, the password is time based and can only be used once.
