Über Passphrasen-Generator
The GuruAlpha Passphrase Generator creates memorable yet secure passphrases from random dictionary words. A passphrase like "correct-horse-battery-staple" is easier to remember than a random string like "xK9#mP2$vL" while providing equal or greater security due to its length.
Passphrases were popularized by XKCD comic #936, which demonstrated that four random dictionary words provide more entropy than a complex 8-character password, while being significantly easier to remember. The Passphrase Generator implements this approach with additional security features.
The generator selects words from a curated dictionary of common English words. Each word is chosen using cryptographic randomness, ensuring that the passphrase cannot be predicted. The number of words (3-8) determines the entropy — four words provide approximately 52 bits, five words provide approximately 65 bits, and six words provide approximately 78 bits.
The tool offers customization options: word count (3-8), word list (common, extensive, technical), separator character (hyphen, space, period, underscore), capitalization (lowercase, Title Case, random) and number inclusion (append a random number for extra entropy). These options let you tailor passphrases to specific requirements.
The strength analysis shows the passphrase's entropy, estimated crack time and comparison to traditional passwords. A six-word passphrase with random capitalization and a number provides approximately 90+ bits of entropy — stronger than most complex passwords while being easy to remember.

Häufig gestellte Fragen zu Passphrasen-Generator
How secure is a passphrase?
A 5-word passphrase provides approximately 65 bits of entropy. A 6-word passphrase provides approximately 78 bits. Both are stronger than complex 8-character passwords.
Can I remember a passphrase?
Yes. That's the advantage of passphrases. Create a mental image connecting the words — for example, imagine a correct horse near a battery and a staple.
What word list should I use?
Common for maximum memorability. Extensive for more word variety. Technical for IT professionals who want jargon-based passphrases.
Are the words from a known list?
Yes. Words come from standard dictionaries, but the selection is random and the combination is unpredictable. An attacker would need to try billions of word combinations.
