Pam_userpass is a software that utilizes PAM binary prompts to obtain both the username and password from applications.
To overcome this flaw, many have made the assumption that PAM_PROMPT_ECHO_ON requests the username and PAM_PROMPT_ECHO_OFF requests the password. But with the innovative pam_userpass, this assumption is no longer required.
Pam_userpass comes with PAM binary prompts which allow the application to ask for usernames and passwords specifically. What's more, this efficient tool doesn't perform any actual authentication. Instead, it stacks an actual authentication module after pam_userpass and directs it to use the authentication token (password) that pam_userpass provides.
Overall, if you want to simplify the authentication process for services like FTP and POP3, pam_userpass might just be the software tool that you need.
