Based on 2025-2026 data, Generation Z and Millennials have the highest rates of password reuse and overall poor password hygiene, driven by "password fatigue" from managing numerous accounts. While often assumed to be more secure, younger generations (18–24 year-olds) are actually more likely to prioritize ease of memory over security, frequently using the same or similar passwords across multiple platforms.

When prompted to update credentials, 38% of Gen Z and 31% of Millennials either change just one character or recycle an existing password. It is understandable that young people want to get results with minimal efforts, but such approach leads to very low cybersecurity and high risks of accounts hacking.

In this post, we consider how it is do possible to create and modify multiple super strong passwords with a single symbol change.

Let us, use a private dynamical passwords generator (DPG). We enter a single symbol into the “Key” field, for example “1” and click on the “Go” button.

As the result we get 100 super strong and unique passwords.

Now, let us try to change 1 on 2.

As we can see, the passwords are completely different from the previous passwords and are super strong.

Let us check how strong these passwords are. We go to Bitwarden site https://bitwarden.com/password-strength/ and enter the 100-th passwords.

We can see, that such passwords need centuries to crack by brute force, dictionary attack, and random guess methods.
