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. 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. Memorable word combinations like "Coffee-Cloud-Guitar-82". Easier to remember, yet secure thanks to high entropy.

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. .

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. is a modern browser feature for cryptographically secure random numbers.

Tips for secure passwords

  • Use a unique password for every account for every accountUse a unique password for every account
  • Use a password manager for management for managementUse a Password manager for management zur Verwaltung

  • Change passwords regularly, especially in the event of a security incident
  • Use passphrases for accounts you need to remember

Frequently asked questions (FAQ)

Are my generated passwords saved?
All passwords are generated purely locally in your browser using the Web Crypto API. There is no data transfer. As soon as you close the page, all data is gone.
Are the generated passwords really secure?
We use the Web Crypto API, which uses cryptographically secure random numbers - in contrast to insecure methods such as Math.random(). This is the same standard that operating systems and professional security applications use., which uses cryptographically secure random numbers - in contrast to insecure methods such as Math.random().

Can I save the passwords?
The passwords are not saved. However, you can copy generated passwords to a password manager of your choice using the copy function.
What is the difference between password and passphrase?
Passwords are short, complex strings (e.g. "K7#mP9$xL2"). Passphrases are longer, memorable word combinations (e.g. "Kaffee-Wolke-Gitarre-82"). Passphrases are easier to remember and still very secure due to their length. are short, complex strings (e.g. "K7#mP9$xL2").
