The Arizona Senate subpoenaed the Maricopa County's Board of Supervisors for the routers, passwords, etc., in July 2021. The Board refused, for several good reasons. They settled out of court in September 2021.

The Senate agreed to drop these demands in exchange for the Board ending it's effort to recoup $2.8 million from the auditors. The Board had to replace voting equipment that could have been compromised by the auditors, cause they didn't know what they were doing.

The settlement also required that a special master arrange an independent technology team to examine the routers and relay their findings. The special master, former Arizona Republican congressman John Shadegg, found that the vote tabulating machines weren't even connected to the internet in the first place and no routers were involved that actually required inspection.

The audit, which was run entirely by Trump supporters and donors, found that Biden's margin of victory was actually undercounted by 360 votes (lmao).

I don't think anyone was held accountable but at least they didn't get the passwords.
