If you pay attention at the end of the episode, Watts mentions that not only has the security code for Mantle not been updated (it has been in Atlas); he helped write the outdated code.

THAT is why he has so much control over the systems in Mantle. He also appears to have specific a specific program or override keyed to each of his rings; which means he has a finite number actively available when not seated at a computer.
