Samsung Smart TV - impossible to login when Facebook's 2FA is on

[ginden]

How to reproduce issue:

- setup two factor authentication on your Facebook account ( https://www.facebook.com/settings?tab=security&section=two_fac_auth )

- try to login to Spotify on Samsung Smart TV (I checked mine that I bought in 2014)

Expected result:

- login form to enter security code

Current result:
- Invalid password or username (?!)

Temporary workaround:
- disable 2FA from your PC
- login on TV

- enable 2FA from your PC
