Can't login with 2FA on Facebook

[nanny07]

If you have 2FA enabled on your Facebook account, you can't login

Not too sure what the best way to address this would be.

Some options I can think of:

1. Turn off 2FA for Facebook (not ideal for those wanting to use 2FA)
2. Perform manually login using 2FA, fetch cookies and store them in config file which then gets used by the script long term. You'll still have to manually update the cookies from time to time when they expire.
3. Store your Facebook 2FA secret in the app/script so the app can generate 2FA codes for Facebook and perform the login itself.

None of these are really ideal. If you have other ideas let me know.

Option 2 might also solve the cookie login problem, I'm willing to try it out to see if that fixes things

Maybe an user can create an App Password that is unique for this. With app password you haven't to insert the 2FA code

[nanny07]

I've tried with the App Password but it can't login:

It only say:
Failed to authenticate with Facebook. Please check provided email/password.

Same problem over here. Disabled 2FA but I still get the error: "Failed to authenticate with Facebook. Please check provided email/password."
Tried App password like nanny07 suggested but didn't work either.

Hmm I couldn't get their app passwords to work for me either. I don't think they allow directly logging into a Facebook account anyway. It seems like its a different concept to regular 'app passwords' which simply act as login credentials that don't require 2FA authentication.

I don't know what 2FA is. When I follow your readme I give this error:
fb2cal ERROR (main) Failed to authenticate with Facebook with email luca.casarin@outlook.it. Please check provided email/password.
Traceback (most recent call last):

@gioluca2
2FA is two factor authentication.
Are you a European user? If so, your login may be failing due to a bug that was just fixed in #4. Try downloading code again and following the steps.

Still can't run the script:

I tried to reset all cookies from facebook but I still don't see that banner when I access facebook.com/login.php for the frist time. The cookies stored are:
c_user
datr
fr
presence
sb
spin
wd
xs

Can you try it with Portugues IP please?
Thank you

@ldoench Please avoid commenting on issues if its unrelated.

Turn logging level toDEBUG in config.ini and inspect results or email me logs (my email on github profile page). For general Facebook security stuff, if you manually log out and back into your account Facebook should show you a 'Was this really you" message which you can use to authorise the other machine.

I made a research about this and I found some interesting code that might help to resolve this issue. I think that only saves the cookies when it's successfully autenticated, and that's some kind of what you guys are looking for:
