Did you add email to your account? If yes, then you should receive an email to change your password.
If not, you need to contact their support team to get back your account but you may need to prove that account belongs to you.
My guess for new coins will be - bitcoin cash, XMR, ripple...
On the bottom of the login page there's a "contact" link that shows the e-mail address for support.
Write them and ask for help, it's the usual best way to handle such situations. Of course, you can also wait until Baryom comes online, although, if you have the e-mail set, anybody from support could help you and it could be faster.
