The young actress, 26, was a relative unknown until landing the role of Anastasia Steele in the blockbuster movie adaptation of E.L. James' erotic novel trilogy, turning her into a household name overnight.
While the movie broke box office records, not everyone was a fan.
Dakota, however, doesn't care, telling the new issue of Vogue: "I'm proud of Fifty Shades of Grey. I don't need to distance myself from that.
"The more work I do, the more the general public sees the different things I can do. Do I think it opened doors? Yeah. More people know my name."
Dakota is the daughter of actors Melanie Griffith and Don Johnson. Her grandmother is the legendary actress Tippi Hendren.
In the same interview, the star hits out at "brutal" ageism in Hollywood, pointing to how both her mother and grandma no longer appear regularly on screen.
"Why isn't my mother in movies? She's an extraordinary actress! Why isn't my grandmother in movies? This industry is f**king brutal. No matter how tough you are, sometimes there's the feeling of not being wanted. It's absurd and cut-throat."
We'll next see Dakota in the big screen comedy How To Be Single, co-starring Rebel Wilson. It arrives in cinemas this Valentine's Day.
