Password strength is of the utmost importance, whether you realize it or not. Some of us might rely on a trusty ol’ password–the first complicated one we ever created, or something that we use for literally everything. As reported on ReadWrite, a study from Concordia University has shown that password strength measurements can be inconsistent, ultimately causing more confusion when trying to create a truly strong password.
Basically: what works for one website might not work for another. Password strength is relative. Even if your password is acceptable for one site (Facebook, PayPal), it may not be acceptable for another (your bank, your credit card). Creating a strong password can be frustrating, especially considering the fact that we are expected to change our passwords from time to time.
