Apparently someone reverse engineered the firmware[0] to find it. I don't see how they could easily change the password, except for perhaps using a custom tag that would only allow incrementing the values with the existing password (which would negate the point of changing the password). Otherwise it would lock existing brushes out of saving the time too. This, combined with how 99% of the users won't be tevh-savvy enough to know how to write to the tag, means there's probably not gonna be any change until they come up with a new incompatible type of brushes.
