We're currently in the process of updating our Facebook sign-in component and will have it in working order as soon as possible.
In the meantime you can still sign in with your Folksy email address and password (or with Google).
If you've only ever signed in with Facebook you can set a password for your account here. This won't affect your ability to sign in with Facebook in the future.
We're sorry for any inconvenience and are aiming to have Facebook sign in working again as soon as possible.
We don't post anything to your timeline, or use your information for anything other than signing you in to Folksy.
