Towards the end of the game, it's revealed that Ted Faro possesses a security clearance level ("Omega", which seems to elicit surprise from at least some team members) that exceeds those of other 'Alpha' team members and presumably even Elisabet's 'Alpha Prime' clearance. He exploits this to
seal the remaining 'Alpha' members in a room, block their system access, murder them by venting the atmosphere, and delete APOLLO.
My question is, how did he get this elevated clearance level? Elisabet appears to despise him and certainly seems far too intelligent to deliberately trust him with any such thing. She basically
blackmails him into funding Zero Dawn and handing her complete control over the project.
So where did his access level come from? Did Elisabet set it up for him? One of the other team members?
Is there a text or audio datapoint that explains how Ted Faro ended up with so much power within the Zero Dawn project?

Out of game answer
Per my question on HZD: Anniversary AMA, Ben McCaw confirms that Omega Clearance is the backdoor Ted mentions to GAIA and, rather than having GAIA create this, he would tasked his engineers to implement this without Sobeck's knowledge.
(Partial) In game answer
As @Vemonus's answer clearly lays out, there is no in-game explanation of how Ted obtained Omega Clearance. The only solid evidence we have of Omega Clearance existing is the Emergency Record.
There is, however, another audio recording with Ted yelling at his engineers for not implementing a backdoor into the Faro Robots: Entangled Waveforms.
So naturally, Ted would have wanted a backdoor into an investment in the event he lost control. GAIA agrees to Ted's proposal for creating a back door, but Sobeck disagrees and we never heard anything else relating to this discussion.
Due to Sobeck's reluctant attitude towards this, Ted would have went around her and tasked his engineers to create Omega Clearance. Since GAIA initially agreed with Ted, I doubt she would have considered this a suspicious act
