Instagram password solution

Hey everyone,
I would like to ask about Instagram account, and how to connect it with MassPlaner.
The account I use at Instagram is connectect with my facebook account, I have created it via FB. To log in I use only 'Log in as facebook'. I did not ever created a password for this account.
Does any know how and if it is possible to create password for instagram accoun since I never had this password before ?
I tried to 'reset password' via mail and did not get any respond.

Email is the solution of getting password but as you said that you didn't get respond from them. I think you have to try again and use gmail account for getting faster response. I hope they'll respond you very soon.

Ok i changed mail for gmail one, and get respond. But it sayst that i have to type my old password which i never had
