A federal judge ordered Christopher Chaney, 35, to appear in a California courtroom on November 1 to answer charges, a spokeswoman for the U.S. attorney's office said.
"What I'm most sorry about is that I had to drag my mom into all of this, and my family and my neighbors and they just want to live their lives," Chaney told reporters. He did not respond to questions.
Chaney is accused of hacking into the accounts of more than 50 celebrities, including movie stars Scarlett Johansson and Mila Kunis and singer Christina Aguilera.
A grand jury indicted Chaney on nine counts of computer hacking for gain, eight counts of aggravated identify theft, and nine counts of illegal wiretapping. If convicted of all 26 counts, Chaney would face a maximum of 121 years in federal prison, U.S. Attorney Andre Birotte Jr. said.
The aggravated identity theft charge alone carries a mandatory two-year prison sentence, he added.
The suspect's attorney, Christopher Chestnut, said his client "remains very remorseful" and understands the importance of privacy.
Still, Chestnut indicated the potential sentence appeared harsh.
"People who murder kids don't get 120 years in prison," he said.
Earlier this week, Chaney told a reporter that he had became "addicted" to the intrusion and "didn't know how to stop."
"I know what I did was probably one of the worst invasions of privacy someone could experience," Chaney told CNN affiliate WAWS/WTEV in Jacksonville, Florida, on Wednesday.
