Let the user set a password (If registered with facebook)

[Il_Picasso]

Hello! 

 

Here is my problem

 

I use tapatalk application for my forum where it asks for username and password.

Everything is good, however I also have enabled so users can log in with facebook, twitter, steam and google which is a problem because this kind of applications asks for an username and password. The user does not have a password.
I wrote a ticket to support to see what I could do, their response was that I could set a password for them through the ACP or they could request as they lost their password.

My suggestion is simple, allow the user to set a password in their settings www.domain.com/settings/ when they don't have it
