Fun Fact! Elon Musk reportedly helped Larry Ellison reset his Twitter password after the billionaire said he'd invest $1 billion in the company, despite not tweeting in 10 years

Elon Musk reportedly helped longtime friend and Oracle cofounder Larry Ellison reset his Twitter password after the billionaire forgot it.

Walter Isaacson – who spent two years trailing Musk – wrote in an excerpt from his upcoming biography on the billionaire, which was published by The Wall Street Journal on Thursday, that he personally got the password reset for Ellison after he pledged to invest in Musk's Twitter takeover. Ellison hasn't tweeted since 2012.

Ellison said he would put $1 billion toward Musk's $44 billion acquisition of Twitter, now X. Ellison and Musk had been friends for some time before the deal and the Oracle cofounder believed the platform was important, according to the book.

"It's a real-time news service, and there's nothing really like it," Ellison told Isaacson. "If you agree it's important for a democracy, then I thought it was worth making an investment in it."

Representatives for Musk did not immediately respond to Insider's request for comment, made outside normal working hours.

Ellison has been a vocal supporter of Musk over the years and has previously sat on the board of Tesla. Musk cofounded the company and is currently its CEO.

Ellison reportedly supported Musk through various stages of his chaotic Twitter takeover. When Musk tried to back out of the deal last year, he was texting with Ellison all night and "into the early morning hours" before he said his $44 billion agreement to purchase the company was "temporarily on hold," Twitter's lawyers said in a court filing.

However, the friendship between the two hasn't spared Ellison's company Oracle from Musk's refusal to pay various expenses for X. Oracle went months without being paid for services rendered last year, two unnamed sources told Insider's Kali Hays.

Musk has refused to pay several other bills at X, including Google and Amazon for cloud services as well as office landlords.
