Oath Keeper Hackett became particularly meticulous about secrecy
during this period, according to prosecutors. When he used the Oath
Keeper GoToMeeting channels, he'd sign in—under his Ahab
pseudonym—through a virtual private network (VPN). Instead of placing
calls or texts through his ordinary carrier, AT&T/TracFone, he used an
app on his iPhone called TextMe. He then associated his Signal account
with his TextMe phone number, rather than his AT&T number. His TextMe
account was, in turn, registered to his encrypted Protonmail email
address, which was listed under a false name, John Willow.
