Changing the way to sign in

[EVR]

When I first created a Zoom account, I used my Facebook account to sign in. Since then I am having to go through Facebook  every time I sign in. I want to create a separate password for my Zoom account and use it for signing in. I am not able to do that because in the Sign In section of My Profile, the Edit option is available only for the email address, not the password. How can I now create a separate password for Zoom and avoid using my Facebook account?
