Password strength is a measure of the effectiveness of a password in resisting guessing and brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability.
If you value your privacy, you must learn how passwords work, how the attacks that attempt to break them work and finally how to choose a strong password that won’t break no matter what you throw at it.
Most people don’t have a proper system for managing passwords. They pick the easiest password that they can remember and probably reuse it in multiple places. In this tutorial we’ll take a look at why this needs to change and how to replace this ad hoc process with a secure and more convenient approach.
