A folk ballad backed by an acoustic guitar, the song is a plea for people to stop abusing their authority, and it mainly addresses men who exploit vulnerable women.

Named one of the best songs of 2021 in Variety and The Guardian, "Your Power" was praised for its candid songwriting, the emotional impact of its critiques of abuse, and the relevance of its lyrics to contemporary society.

She first performed the song live on The Late Show with Stephen Colbert, and she included it in the set lists of a 2021 concert film and a 2022–2023 world tour in support of Happier Than Ever.

Eilish also performed "Your Power" to protest the overturning of Roe v. Wade by the US Supreme Court, a landmark decision that removed abortion's status as a constitutional right in the country.

[5] Its lyrical themes include the unhealthy effects of fame and the struggles that young women experience in the entertainment industry, such as misogyny, power imbalance, and emotional abuse.

[9][10] A day after the announcement, Eilish posted a nine-second snippet of the song to her social media accounts and previewed the visuals for its music video.

[13] In the caption for an Instagram post that accompanied its release, Eilish said it was one of her favorite songs she had written and its candid and confessional lyrics made her feel vulnerable.

[20][21] Dubbing "Your Power" as an "open letter to people who take advantage", Eilish explained that it sought to discuss the confluence between sexual misconduct and body image.

[31] Other critics compared it to songs by soft rock band America,[34] indie folk singer Phoebe Bridgers,[26][35] and artists from the Laurel Canyon music scene[36] based on its acoustic production and personal lyrics.

The song is a plea for people to stop abusing their authority—it mainly focuses on men who take advantage of young and vulnerable women,[37] though Eilish wanted it to apply to exploited teenage boys as well.

[26] Becky Zhang of Los Angeles magazine commented on the similarities between the music videos for "Your Power" and for Britney Spears's "I'm Not A Girl, Not Yet a Woman" (2002).

Zhang also drew parallels between the social contexts in which the videos were made, arguing that Eilish and Spears were asserting their agency and independence as teenage girls transitioning into young adult women in a society dominated by the male gaze.

[56] Music critics praised "Your Power" for its candid and confrontational songwriting, underscoring the emotional impact of its critiques of abuse and the relevance of its lyrics to contemporary society.

[b] For Jackson Langford, writer at MTV Australia, the qualities that made the lyrics strong were its "clarity, conciseness and its inability to be interpreted in any other way than what was intended.

"[61] In four-star reviews of the song, NME's Rhian Daly and The Guardian's Alexis Petridis argued that the juxtaposition between its message's impact and simple, straightforward nature made the lyrics memorable.

Petridis compared the "matter-of-fact" nature of the chorus to "reminding someone to take their house keys with them" and concluded that this approach was intentional because powerful people should not have to be told not to abuse their positions of authority.

"[24] Other critics found the lyricism in "Your Power" a testament to Eilish's songwriting skills, which Jason Lipshutz of Billboard thought was "underrated [and] overshadowed by the other facts of her superstardom".

[24][35][44][63] This led two critics to deem the song tantamount to a "real-life horror story", comparing it to the fictional, sinister narratives and "spooky" sounds of When We All Fall Asleep, Where Do We Go?

One of them, Pitchfork's Quinn Moreland, argued: "While Eilish's first album was full of overtly scary thoughts—stapled tongues, monsters under beds, teen suicide—the reality presented on 'Your Power' is profoundly more haunting.

"[64][65] Several critics placed the song within the context of #MeToo, a social movement started by women to expose and counter sexual misconduct by men in positions of power.

[31][70] For Giselle Au-Nhien Nguyen of The Sydney Morning Herald, the "clever trick" that made this difference in tone effective was that "the delivery of these cutting sentiments often sounds sweet, which makes them feel somehow even more acidic",[73] while in Petridis's view, the dissonance works because the "chilling air" that Eilish evokes gets "under your skin rather than in your face.

Daly wrote: "In keeping things stripped back the song draws you into an intimate space, as its creator confronts you with her haunting voice and uncomfortable tales.

[79] For her acceptance speech at the VMAs, Eilish called attention to women's rights issues, one of three musicians in the ceremony who made references to contemporary politics.

[86][87] UK listeners streamed "Your Power" 2.1 million times in the first half of its opening week, making it the country's number 1 trending song during the period and setting it on track for a top 10 debut.

[89][90] In Australia, it was her twelfth top 10 song;[91] on the singles chart published by the Australian Recording Industry Association (ARIA), "Your Power" debuted at its peak position of number 9.

[102][103] Eilish hoped to reinforce the stories present in Happier Than Ever's songs through visual media, using the official live performance for "Your Power" as an opportunity to do so.

[104] After the album's release, Eilish performed "Your Power" in Happier Than Ever: A Love Letter to Los Angeles, a concert film that premiered on Disney+ on September 3, 2021.

[113][114] During that year's Glastonbury Festival, Eilish performed "Your Power" to protest the overturning of Roe v. Wade by the US Supreme Court, a landmark decision that removed abortion's status as a constitutional right in the country.
