You can request a password reset using the e-mail account associated to your Google+ account.
You can click on the grey question mark in the password field.
We will send you a link to "reset" your password, and once you follow the steps, you'll have a password attributed to your account which you can then use to log-in.
We are required to support G+ log-in on the mobile apps, but have not applied that to the desktop version of the app. Hope that helps!
