How to create a strong password (and store it safely)
Length beats complexity theater. Learn what makes a password strong, how browser generators help, and why a password manager matters.
What “strong” actually means
Attackers rarely guess your password by hand. They use leaked lists, common patterns, and automated guessing. A strong password is long, unique to each site, and unpredictable—not necessarily packed with every symbol if that makes it hard to type or remember.
A 16–20 character random password from a generator is usually stronger than a short clever phrase you reuse across accounts.
Use a generator, then a manager
Generate the password in your browser (so it never travels to a third-party “password API”), copy it once into a reputable password manager, and let the manager autofill later. Do not email passwords to yourself or save them in plain notes apps.
Our password generator uses the Web Crypto API on your device. Pair it with the strength checker as a quick sanity check—not as a guarantee against every attack.
Habits that matter more than symbols
Never reuse passwords. Turn on multi-factor authentication where available. Change a password immediately if a service announces a breach. Prefer passkeys when a site supports them.
