“But, Adams further claimed, he had forgotten the password he had just set, and thus was unable to provide the FBI with a password that would unlock the phone.”
You know, the same thing happens to me every time the FBI takes my phones.
Apple has a feature to restrict changing the passcode when not in a typical geolocation. This is to prevent thieves from shoulder-surfing your passcode in a bar and then snatching the phone and changing the code. If you’re at home or at work (where the phone recognizes your typical behavior / location), it shouldn’t activate. In a random location, it would. I don’t know how well that works. It’s a relatively recent feature (within a year or so, I think).
