I'm a little paranoid about getting locked out of my account because what if the automated service provider thinks I'm not who I claim to be? Hence I see the advantage of being able to reset passwords in person. What I prefer is being able to reset it online, but also having the ability to physically go somewhere and reset it in person as a last resort. Also, wouldn't this (in-person reset only) be hard to scale beyond a certain point? If there's a million users, and 0.1% (¯\_(ツ)_/¯) needs to reset their password everyday, that's 1000 resets everyday. On an 8 hour workday, there's 480 minutes; you'll have to verify and reset a little more than two people every minute. Or you could hire more people, which raises costs. This is hard to scale.
