In addition to a secure password, so-called two-factor authentification provides additional security. In the process, a second, independent security component is requested in addition to the first one (generally a password). This might be a code sent to your mobile phone or generated directly on your device.
Nowadays, it is not just financial institutions, but also many online service providers (such as Google, Facebook) who offer two-factor authentification. You should avail yourself of this increased level of security. A description of all the different methods used by financial institutions can be found here.
