First families get their Secret Service code names at the very beginning of a presidential campaign.
Presidents get to choose from a list provided by the White House Communications Agency.
The code names are for security purposes, but they often get leaked or are overheard at events.
Secret Service code names, which Secret Service agents use when communicating about the security of the first family, are among the worst-kept secrets in Washington.
Though they're meant to be secret, the code names quickly become public either through government filings, sources who leak them to news outlets, or when agents are overheard at public events. Since new technology has allowed security agents to monitor officials in a variety of ways, the names aren't so top-secret anymore.
The White House Communications Agency assigns each member of the first family a code name for Secret Service agents to use during their time in the White House. These names come from a list of agency-approved choices that either the president chooses from or agents pick.
Other members of the family are then assigned names that share the same first letter. Sometimes, it's the same letter as the family's last name, but not always.
Here are the Secret Service code names used by the past 12 presidents and first ladies.

Kennedy's code name harkens back to Lancelot, one of King Arthur's heroic Knights of the Round Table. After his death, Jacqueline Kennedy popularized the moniker "Camelot" in reference to his presidency.

Jacqueline Kennedy's code name was fitting for her image as one of the most elegant residents in the history of the White House, who wore lace for her high-profile wedding and during events like a widely covered state visit to France.

Carter's open devotion to his Christian faith made this codename spot-on. After his retirement from politics, Carter even spent time teaching Sunday school.

Though he said in a 2015 candidate debate that he would choose the name "Humble" for himself, the one he was ultimately assigned was likely inspired by decades spent in a real-estate dynasty handed down from his father. Trump has used the same code name during both of his terms.

It's been suggested the first lady's name refers to her career in front of the camera as a model in New York City before she met her mogul husband.
The name of Melania Trump's production company, Muse Films, is a nod to her Secret Service code name. Muse Films will release the documentary "MELANIA," which chronicles the lead-up to Trump's 2025 inauguration, on January 30.
