Go to: Communities >> Set Up >> Security To enable code based signup you have to enable the "Code Based Signup" option under Security settings option for the panel.
Once you have enabled the code based sign up setting for your panel the "Passcode" field will be asked on the sign up form. Only passcode that matches to the one that you set for the panel is accpeted for registration. This way your panel is not a public panel and only members whom you share your passcode with can access/ register to the panel.
When the SSL Option is checked, the links for the surveys are automatically encoded using SSL (Secure Socket Layer) the industry standard encryption technology. This makes sure that no one else has access to the data and adds another added layer of security. The SSL technology encrypts data that gets passed between our servers and the end-user -- survey respondent.
Secure Socket Layer (SSL) is a cryptographic protocol that provides communication security over the Internet. Hypertext Transfer Protocol Secure (HTTPS) is a widely-used communications protocol for secure communication over a computer network, with especially wide deployment on the Internet. Technically, it is not a protocol in itself; rather, it is the result of simply layering the Hypertext Transfer Protocol (HTTP) on top of the SSL protocol, thus adding the security capabilities of SSL/TLS to standard HTTP communications.
HTTPS provides authentication of the web site and associated web server that one is communicating with, which protects against Man-in-the-middle attacks. Additionally, it provides bidirectional encryption of communications between a client and server, which protects against eavesdropping and tampering with and/or forging the contents of the communication. In practice, this provides a reasonable guarantee that one is communicating with precisely the web site that one intended to communicate with (as opposed to an impostor), as well as ensuring that the contents of communications between the user and site cannot be read or forged by any third party.

When a new member signs up for community and enter their email address, an email is sent to the member. The email contains the email verification link. The new member will have to click on the link to verify their profile.
If the new member does not click on the link sent via email, the member would not be able to login because its a verification process to verify a genuine email address for security reasons.
Once this option is enabled, a new member would be able to see captcha verification while sign up.
