Cryptographically Secure Password Generator
Generate passwords with military-grade security using advanced cryptographic techniques. True randomness guaranteed with no predictable patterns.
How Our Security Works
Random Selection
crypto.getRandomValues() generates true random numbers
Bias Elimination
Rejection sampling ensures uniform character distribution
Character Guarantee
At least one character from each selected type
Secure Shuffling
Fisher-Yates algorithm prevents pattern detection
Technical Implementation
Cryptographic Randomness
Web Crypto API
Uses browser's native cryptographic functions
Entropy Source
Hardware-based random number generation
Uniform Distribution
Rejection sampling eliminates modulo bias
Security Guarantees
Character Inclusion
Each selected type guaranteed in output
Pattern Prevention
Cryptographic shuffling prevents sequences
No Predictability
Each password is completely independent
Security Standards
NIST Compliant
Follows NIST SP 800-90A guidelines for random number generation
FIPS 140-2 Level
Uses cryptographic modules meeting federal security standards
Military Grade
Entropy quality suitable for military and government use
Complete Privacy Protection
Client-Side Only
All password generation happens in your browser - nothing is transmitted
No Logging
Passwords are never stored, cached, or logged anywhere
No Analytics
Password generation process has no tracking or monitoring
Zero Knowledge
We never see your passwords or have any way to recover them
