How to Create a Strong Password (2026 Guide)

A strong password is long (at least 12–16 characters), random, and unique to each account. Length matters far more than swapping an "a" for "@" — a long random passphrase beats a short complex one every time. Here's how to create and manage them, with a free password generator.

What makes a password strong

• Length — every extra character multiplies the guessing time; aim for 16+.
• Randomness — no names, dates, or dictionary words a computer can guess.
• Uniqueness — one breach shouldn't unlock your other accounts.

Generate a long, random one instantly with the Password Generator — it runs in your browser, so the password is never sent anywhere.

Passphrases: strong and memorable

For passwords you must remember, string together four or more random words (like correct-harbor-velvet-mango). They're long enough to be very hard to crack yet far easier to recall than a jumble of symbols.

The habits that matter more than complexity

• Use a password manager so every account gets a unique password you don't memorize.
• Turn on two-factor authentication — even a leaked password is far less useful without it.
• Never reuse passwords across sites.

Bottom line

Long, random, and unique wins — generate one free with the Password Generator, store it in a manager, and add two-factor authentication.
