Flint, who came through the youth ranks at the Mornflake Stadium, has put pen to paper over an initial one-year deal, with the Whites holding the option of a further 12 months.
He will now provide competition for Luke Hutchinson and Ellis Litherland in Matt Craddock’s squad.
“I’m buzzing to be signing and I’m delighted to be here. I’ve worked really hard to get to this point so I’m really happy to sign,” Flint told the club website.
“I’m looking forward to working hard with the B Team to keep progressing.”
He added: “As a goalkeeper I think I’m a good shot-stopper and have quick reactions. When I was at Crewe, I had to be good with the ball at my feet so I’m comfortable doing that too.
“I’ve just got to work as hard as I can, put everything I’ve got into it and hopefully progress.”
Flint is available for this afternoon’s Central League opener against Preston North End at the Euxton training ground (2pm). Supporters are welcome to attend the fixture and entry is free of charge.
In addition to their Central League schedule, Craddock’s side will again take part in a programme of hand-picked friendlies against other B Teams and Academies over the coming season.
The young Whites enjoyed a productive pre-season campaign against a variety of opposition, including several local non-league sides.
