How to Create a Strong Password (That You Can Actually Manage)
Most passwords fall for one of two reasons: they are short enough to brute-force, or they are reused — so one leaked site unlocks every other account. Both problems are easy to fix. This guide explains what "strong" really means and gives you a system that does not rely on memory gymnastics.
What makes a password strong
- Length first. 16+ characters matters more than any clever substitution. "P@ssw0rd!" is weak; a long random string is not.
- Randomness. Names, birthdays, teams and keyboard walks (qwerty, 12345) are the first things attackers try.
- Uniqueness. Every account gets its own password. Reuse is how one small leak becomes a total takeover.
Step by step: generate one properly
- Open the Password Generator on NToolHub.
- Set the length to at least 16 (20 is better) and keep letters, numbers and symbols all switched on.
- Generate, copy the password, and save it in your password manager before you use it.
- Repeat for your important accounts — email first, since email resets everything else.
No password manager yet? Your browser’s built-in manager (Chrome, Safari, Edge) is a fine start and syncs to your phone. Anything is better than one password everywhere.
The honest rules
- Never share passwords over chat or email.
- Turn on two-factor authentication (2FA) for email and banking — it blocks most attacks even if a password leaks.
- Do not "rotate" passwords on a schedule; change them when there is a leak or a reason, not by the calendar.
