Password Generator
Generate secure passwords, PIN codes, and random IDs.
Understanding Passwords and Secrets
What are Passwords and Secrets?
Passwords and secrets are strings of characters used to authenticate users and protect sensitive information. They come in various forms:
- Passwords: User-created strings used to authenticate access to accounts and services
- PIN Codes: Numeric codes used for quick access to devices or services
- Random IDs: Unique identifiers used in applications and systems
How We Generate Secure Values
Our generator uses cryptographically secure methods to create truly random values:
- Uses the Web Crypto API for secure random number generation
- Implements industry-standard algorithms for ID generation
- All generation happens in your browser - no data is sent to servers
- Uses the EFF diceware wordlist for generating strong passphrases
Word Passphrases and Entropy
Our word-based passphrases are generated using the Electronic Frontier Foundation's (EFF) diceware wordlist, combined with modern cryptographic libraries. This approach provides several security benefits:
- High Entropy: Each word adds significant entropy to the passphrase, making it extremely difficult to brute force
- Memorable: Word-based passphrases are easier to remember than random character strings
- Proven Security: The EFF wordlist is specifically designed for generating secure passphrases
- Cryptographic Randomness: Words are selected using cryptographically secure random number generation
For example, a 4-word passphrase from our generator would take many years to brute force, even with modern computing power, while remaining relatively easy to remember.
Best Practices for Using Generated Values
When using generated passwords and secrets:
- Store them securely in a password manager
- Never share them through insecure channels
- Use different values for different services
- Regularly rotate sensitive credentials
- Consider using passphrases for better memorability
Types of Generated Values
Passwords
Two types of passwords are available:
- Random Characters: Mix of letters, numbers, and symbols for maximum security
- Word Passphrases: Multiple random words for better memorability while maintaining security
PIN Codes
Numeric codes suitable for:
- Device access codes
- Temporary access tokens
- Quick authentication needs
Random IDs
Three formats available:
- CUID: Collision-resistant unique identifiers
- UUID: Universally unique identifiers
- Nano ID: Compact unique string IDs
