Reports on Wednesday suggested Scolari's appointment was imminent, and on Thursday the Brazilian Football Confederation confirmed the coach's return to the national side.
Scolari led Brazil to their last World Cup title in 2002 and will now be in charge when the five-times winners host the tournament in 2014.
The former Chelsea boss has been without a job since he left Palmeiras in September, having previously led Portugal at the 2006 World Cup and 2004 and 2008 European Championships.
"I feel more motivated, younger, I feel I'm capable," Scolari said. "We have the obligation to win the title; we are not favourites at the moment but we intend to become favourites during the competition. Third or fourth place is no good for a country that has won five World Cups.
"I'm not feeling under pressure, but very happy. When the FA president (Marin) called me last Tuesday and confirmed that I was the chosen one, I thanked him a thousand times.
"I was under pressure the first time, when we were in danger of not going to the World Cup. The players are those who always have pressure over them, I don't.''
Pep Guardiola was also under consideration for the role, Brazilian Football Confederation president Jose Maria Marin revealed, but Scolari's past international achievements proved a deciding factor.
He will be assisted by another World Cup winner with Carlos Alberto Parreira, who led the team to glory in 1994 in the United States, coming in as general manager.
Marin said: "After a lot of analysis, thinking about what would be the best for Brazilian football, for the Brazilian fans, we decided to give the responsibility of the national team for the Confederations Cup (next summer) and the World Cup to two great champions, respected throughout the world, Felipe and Parreira.''
Parreira added: "It's our job to get the fans to fall in love with the team. We have to make them feel proud of the national team. That's what we want. The team should feel at home.''
Scolari's first match in charge will be a friendly against England at Wembley on February 6.
