Some time ago Twitter announced the addition of two-factor authentication security feature to each account.
In every account except those of Greece, as the service it did not work with Greek phones (++30).
From today the service is also active in Greece and you can enjoy more better safety to your account, in exchange for giving your phone number to Twitter.
You can add your phone number from your account settings, specifically from the following link:
https://twitter.com/settings/add_phone
After adding it, you will receive an SMS containing a confirmation number, which you should type in TWitter.
You are ready, as of today you can also enjoy the service.
