About this tool
Generate cryptographically strong passwords using the browser's secure random generator (crypto.getRandomValues). Choose between XKCD-style passphrases — memorable word combinations following NIST password guidelines — or traditional character-based passwords with configurable length, symbols, digits, and case. Passphrases are often more secure and more memorable than short random strings. All generation is local — nothing is transmitted to any server.
Questions and answers
- Are the passwords generated securely?
- Yes, all passwords use crypto.getRandomValues, the browser's cryptographically secure random number generator.
- What are XKCD-style passphrases?
- XKCD passphrases combine multiple random common words (e.g., "correct horse battery staple"), which are often both more secure and more memorable than short random-character passwords.
