How does it work? Short answer.
The client tries to provide special DNS records after the user has entered an email adress into the mail client configuration. In case this fails, then the user is led trought the standard configuration procedure . But if valid records have been provided, then the client uses the returned configuration and doesn't bother the user with any complicated questions.
Is the user password sent to the autoconfig server?
No, the user password is never sent to the autoconfig server, the password is sent only to ones mailserver.
How should the DNS records for the domain look like?
For Thunderbird:

autoconfig IN CNAME
