How to reproduce issue:
- setup two factor authentication on your Facebook account ( https://www.facebook.com/settings?tab=security§ion=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
