## Outside of professional soccer
### Philanthropy

Krieger teamed up with the charity MiracleFeet in 2014. MiracleFeet is an organization that works to treat children with clubfoot in developing countries. Regarding her involvement with MiracleFeet, Krieger stated that it "means the world to [her] to be able to have this opportunity to help transform a kid's life."
Krieger also works with Garth Brooks' Teammates For Kids Foundation, where she spends time with children in various programs.
In June 2015, Krieger became an ambassador for the non-profit organization Athlete Ally, which works to end homophobia and transphobia in sports. Krieger believes creating an accepting environment on and off the field, as Athlete Ally strives to do, is important for athletes and is the reason she joined the organization.

### Coaching

Following the 2018 NWSL season, Krieger was one of 21 NWSL players who participated in a series of coaching licensure courses co-sponsored by U.S. Soccer, the NWSL, and Utah Royals FC. Krieger, who earned her U.S. Soccer "C" license following the course, has expressed interest in coaching at the professional or national team level.

### Endorsements

Krieger became a professional athlete with Nike in 2007 and exclusively wears Nike cleats and training gear. Krieger and teammate Sydney Leroux introduced Sydney + Ali's Dynamic Duo Workout on the Nike+ Training Club app in 2014. In 2015, Krieger appeared in the Nike+ Training Club 90-Day Better For It Challenge alongside teammates Carli Lloyd and Christen Press. The campaign combined various Nike+ workouts into a fitness program.
Following the concussion she sustained while with the Washington Spirit in April 2015, Krieger teamed up with Unequal, which makes protective sports gear. When she returned to play following the concussion, she wore a protective headband provided by Unequal.
Krieger teamed up with both ZICO and Smuckers for the 2016 Summer Olympics in Rio. She was featured in a series of promotions as a part of ZICO's Olympic campaign and exclusive content about Krieger would be released by Smuckers, an official sponsor of the 2016 U.S. Olympic and Paralympic Teams.

## Honors

Following the United States' win at the 2015 FIFA Women's World Cup, Krieger and her teammates became the first women's sports team to be honored with a ticker tape parade in New York City. Each player received a key to the city from Mayor Bill de Blasio. In October of the same year, the team was honored by President Barack Obama at the White House.
Krieger was featured along with her national teammates in the EA Sports' FIFA video game series in FIFA 16, the first time women players were included in the game.

## Personal life

Krieger's last name means "warrior" in German, a language she became fluent in during her time with FFC Frankfurt. Her teammates often call her "The Warrior Princess" due to the origin of her name and her personality.
Krieger is very close with her brother, Kyle. He is a YouTube and Instagram personality who has talked openly about his previous drug and alcohol problems. Regarding her relationship with her brother, Krieger has stated: "I have fallen a few times and each time I have gotten up and grown as a person and looked at things a little differently. That is where I have learned so much from Kyle. (Seeing him) struggling through addiction and alcoholism and overcoming that and overcoming adversity, for me that's just an unreal role model in my life. It is like night and day. For two years of my life he was absent, in and out of my life. To look at how far he has come it is just so rewarding to see."
On March 13, 2019, Krieger announced her engagement to longtime girlfriend Ashlyn Harris. Harris is also a soccer player who played with Krieger on the Washington Spirit, Orlando Pride, NJ/NY Gotham, and the national team. The two got married on December 28, 2019, in Miami. On February 14, 2021, the couple announced the adoption of their daughter, Sloane Phillips Krieger-Harris, born two days earlier. On August 16, 2022, they announced the adoption of their son, Ocean Maeve Krieger-Harris. On September 19, 2023, Harris filed for divorce.
