Kanye West may need to change the password on his cellphone after unlocking the device during a televised sit-down Thursday with President Trump at the White House.

The rapper's simple password to his iPhone was caught by eagle-eyed reporters watching the bizarre exchange unfold in the Oval Office.

West was trying to find a photo on his cell of a new aircraft to use as an example of how the U.S. deserved the best, "including the freshest, the flyest, the flyest planes."

"This right here is the I-Plane One," the rapper said. "It's a hydrogen-powered airplane, and this is what our president should be flying in."

"We'll get rid of Air Force One," Trump responded. "Can we get rid of Air Force One?"

West's wide-ranging soliloquy touched on his lack of male role models growing up, a key reason why he was drawn to Trump's "energy" in 2016. He also raised criticisms of how the country deals with mental health and the curricula being taught in U.S. schools.
