Wachtwoord generator

Onze wachtwoordgenerator maakt cryptografisch willekeurige wachtwoorden van elke gewenste lengte met hoofdletters, kleine letters, cijfers en speciale tekens. In een tijdperk van miljarden datalekken per jaar is een sterk, uniek wachtwoord uw eerste en belangrijkste verdedigingslinie. Menselijk gekozen wachtwoorden bevatten altijd herkenbare patronen — onze generator niet.

Test na het genereren direct de sterkte van uw wachtwoord met onze Wachtwoordsterkte Checker. Gebruik nooit hetzelfde wachtwoord voor meerdere accounts — bij één datalek worden alle accounts met hetzelfde wachtwoord direct kwetsbaar.

What makes a password truly strong?

The NIST Special Publication 800-63B (2017) fundamentally changed how security professionals think about password strength. The old paradigm — mandatory complexity rules like "must include uppercase, number and symbol" — turns out to be counterproductive because it leads to predictable patterns (Password1!, Summer2024!). NIST's updated guidance: length matters more than complexity. A 20-character passphrase of random words ("coffee-mountain-river-lamp-27") is far stronger than an 8-character "complex" password and vastly easier to remember. Our generator uses a cryptographically secure random number generator (CSPRNG) — not JavaScript's regular Math.random() which is not cryptographically secure — to generate genuinely unpredictable passwords.

Why you need a different password for every site

Data breaches expose billions of credentials annually. When a site is breached, attackers immediately use the stolen username/password pairs to attempt logins on every major service — a technique called credential stuffing. If you reuse passwords, a breach at one minor site can unlock your email, banking and social accounts. Use a password manager (Bitwarden, 1Password, KeePass) to generate and store unique passwords for every service. After generating your password here, check its strength with our Password Strength Checker.
