What is the difference between an ETIAS and Schengen Visa?

Even though the ETIAS is not yet being used, travelers are concerned whether they will need and ETIAS or Schengen visa. ETIAS is an electronic travel authorization and applies only to people who can already travel to Europe without a visa. On the other hand, the Schengen Visa is required for travel to Europe for those who are unable to travel to EU countries without a visa.
