Random passwords vs. passphrases
Our tool offers two modes for different needs:
- Random passwords: Complex strings with upper/lowercase letters, numbers and special characters. Ideal for maximum security on important accounts.Random passwords: Complex strings with upper/lowercase letters, numbers and special characters. Ideal for maximum security on important accounts. Komplexe Zeichenketten mit Groß-/Kleinbuchstaben, Zahlen und Sonderzeichen. Ideal für maximale Sicherheit bei wichtigen Accounts.
- Passphrases: Memorable word combinations like "Coffee-Cloud-Guitar-82". Easier to remember, yet secure thanks to high entropy. Our word list contains over 800 words – at least 5-6 words are recommended.Passphrases: Memorable word combinations like "Coffee-Cloud-Guitar-82". Easier to remember, yet secure thanks to high entropy. Our word list contains over 800 words – at least 5-6 words are recommended. Einprägsame Wortkombinationen wie "Kaffee-Wolke-Gitarre-82". Leichter zu merken, aber dennoch sicher durch hohe Entropie. Unsere Wortliste umfasst über 800 deutsche Wörter – empfohlen werden mindestens 5-6 Wörter.
Password strength and security

Why is password length more important than special characters?
The security of a password primarily depends on its length. A 16-character password with only letters is more secure than an 8-character password with all special characters. Length increases entropy exponentially, while special characters only contribute linearly. At least 16-20 characters are recommended for important accounts.

Empfohlen werden mindestens 16-20 characters für wichtige Accounts.
What is the Web Crypto API?
The Web Crypto API is a modern browser feature for cryptographically secure
random numbers. Unlike Math.random(), which generates pseudo-random numbers,
the Web Crypto API uses real random processes from the operating system (e.g. /dev/urandom on Linux).
This is essential for password generation, since predictable random numbers represent a security risk.

Tips for secure passwords
- Use a unique password for every accountUse a unique password for every account
- Use a Password manager for managementUse a Password manager for management zur Verwaltung
- Enable Two-factor authentication where possibleEnable Two-factor authentication where possible
- Change passwords regularly, especially in the event of a security incident
- Use passphrases for accounts you need to remember
