Password Security Suite
Generate, analyze, and hash passwords. All client-side except bcrypt.
Generation and analysis happen locally in your browser. Bcrypt hash/verify is server-assisted: the password you enter in that mode is sent over HTTPS to our server, hashed in memory with PHP
password_hash(), and discarded — never stored or logged. Do not use it with a password that is already in use.

Passphrase Generator
Generate memorable passphrases using random words (Diceware-style).
Password Strength Reference
Entropy Levels
- Weak: < 40 bits
- Fair: 40-59 bits
- Good: 60-79 bits
- Strong: 80-99 bits
- Very Strong: 100+ bits
Best Practices
- Use unique passwords for each account
- Aim for 80+ bits of entropy
- Use a password manager
- Enable 2FA when available
- Avoid personal information
Character Sets
- Uppercase: 26 characters
- Lowercase: 26 characters
- Numbers: 10 characters
- Symbols: 32 characters
- All combined: 94 characters
Passphrase Benefits
- Easier to remember
- High entropy with fewer characters
- Resistant to dictionary attacks
- 2048-word list → 11 bits/word
- 4 random words = 44 bits
- 6 random words = 66 bits
