You can also install a plugin in Keepass. I know that a Canadian company, Secure Exchanges, has developed an addin for Keepass that is used to share registration information via secure email. I use it for myself and it works very well.
Your contact will receive a secure email, which you can also protect with a password if you wish, and they will have access to your "password" without you having to share your comic or create a new user.
If you change your password afterwards, they will only receive it if you share it again.
