How many passwords does the average internet user have?

How to get close to this number

Count your own accounts. Email, banking, shopping, streaming, social, work tools, utilities, travel, government services — most people can list forty without effort and have forgotten twice that many. Enumerating categories rather than guessing a total is the reliable approach, and it produces a number around a hundred.

The growth is what makes the figure a problem rather than a curiosity. It has risen sharply in a few years because every service now requires an account, including many that have no need for one. The number of passwords a person has tracks how many businesses decided they wanted a user record, not how many things a person actually does.

The consequence in the explanation is the important one and it follows directly: nobody can remember a hundred distinct strong passwords, so people reuse a handful across dozens of accounts. The reuse is not carelessness, it is an inevitable response to an impossible requirement — which is exactly why a single breach at one service compromises accounts at every other.
