It depends on what you call technically strong. As https://www.xkcd.com/936/ indicates, it is not intuitively clear which passwords are strong. Humans have a terrible instinct when it comes to entropy in data and therefore need to be guided in choosing a password. This often results in a check for length(which is a good thing), but also requirements for capitals, numbers and special characters(which is often used poorly). The result is that people will use passwords like Welcome0! which can be figured out by many people simultaneously and therefore is a weak password.
The 'technical' strength of a password is connected to its entropy. Using a password that satisfies some byzantine requirement, but contains not enough entropy is also weak in the technical sense. "Correct horse battery staple"-like passwords are strong, "Correct horse battery staple" itself is incredibly weak, thanks to mr. Monroe.
