If you normally use Facebook or Twitter to log in and no longer wish to, all you need is your username/email address, and password, and you can use these to log in.
Your username can be found in your Account settings, here, or within your Airbit profile URL (e.g. airbit.com/your-username).
To reset your password, head to airbit.com/login and click the 'Forgot Password' link and a password reset email will be sent to you. Please note - password reset links are only valid for one hour.
You can now log in without Facebook or Twitter!
