Always ON: How can we synch the logins in primary and secondary servers?

Hi,

For Always ON scenario, How can we synch  the logins/passwords in primary(Node1) to  secondary(NOde2) ?

Is there any script to run automatically synch the both logins/passwords?
I know , as standard MS script like sp_help_revlogin ( Transfer logins and passwords).  But, is there any other way, we can synch the logins/passwords in Always ON configured servers?

Thanks
