Passphrase Generator
- Browser-based
- No signup
This passphrase generator creates random word sequences that are long, memorable, and hard to guess. Ideal for master passwords, Wi-Fi networks, and recovery phrases—customize word count and separators, generated locally in your browser.
Passphrases trade symbol complexity for length. Four or more random words often exceed 40 bits of entropy.
Avoid famous quotes or song lyrics—they are in attacker dictionaries.
