Spanish Random Passphrase Generator
Generate secure, memorable passphrases using the Diceware method in Spanish
Our Spanish passphrase generator helps you generate random Spanish passphrases using the Diceware method with a curated Spanish wordlist. Generate-Random.org provides a free Spanish passphrase generator that creates memorable, secure passphrases with 3-10 Spanish words. This multilingual Diceware passphrase generator uses cryptographically secure random word selection for maximum security—perfect for master passwords, cryptocurrency wallets, and high-security accounts. Generate Spanish passphrases that are easier to remember than complex random passwords while maintaining excellent security. Available in English, French, German, and Spanish. No signup required, completely free.

About Diceware Passphrases
Diceware passphrases use randomly selected dictionary words to create secure, memorable passwords. Based on the EFF wordlist with 7,776 carefully chosen words for optimal memorability.
Each word adds ~12.9 bits of entropy. A 5-word passphrase provides 64.5 bits of entropy, equivalent to a 10-character random password but much easier to remember. For even stronger security, try our encryption key generator.
Example: "correct-horse-battery-staple" is stronger and more memorable than "Tr0ub4dor&3"
Passphrase Generator Configuration Options
Word Count (3-10 Words)
- 3 Words (~38 bits): Minimum security, only for low-value accounts
- 4 Words (~51 bits): Basic security, suitable for general-purpose accounts
- 5 Words (~64 bits): Good security, recommended for most important accounts
- 6 Words (~76 bits): Strong security, suitable for financial and sensitive data
- 7-8 Words (~89-102 bits): Very strong, excellent for master passwords
- 9-10 Words (~114-127 bits): Maximum security, military-grade encryption level
Separator Character Selection
- Example: correct-horse-battery-staple
- Widely accepted across all systems and platforms
- Easy to type on all keyboards (no shift key required)
- Improves readability while maintaining word distinction
- Industry standard for passphrase generation
- Example: correct horse battery staple
- Most natural to read and remember
- May not be accepted by all password systems
- Some systems trim or reject spaces in passwords
- Best for systems that explicitly allow spaces
- Example: correct_horse_battery_staple
- Common in technical environments and APIs
- Universally accepted in password systems
- Requires shift key on most keyboards
- Example: correct.horse.battery.staple
- Compact and unobtrusive visual separator
- May be mistaken for file extensions in some contexts
- Easy to type without shift key
- Example: correcthorsebatterystaple
- Creates more compact passphrases
- Harder to read and remember word boundaries
- May improve security minimally by removing predictable pattern
- Can lead to typos when entering passphrase
Capitalization Settings
- None (all lowercase): correct-horse-battery-staple - Easiest to type and remember
- First Letter of Each Word: Correct-Horse-Battery-Staple - Improves readability
- Security Note: Adds ~1 bit of entropy per word if truly random, but predictable patterns add less
- Use Cases: Systems requiring uppercase, improved visual scanning, title-case aesthetic
Numeric Suffix Addition
- Range: Random number between 10-999 (avoids single digits for consistency)
- Entropy Boost: Adds approximately 9.95 bits of entropy (log₂(990) ≈ 9.95)
- Example: correct-horse-battery-staple-847
- Use Case: Systems requiring numeric characters, additional entropy without extra words
- Position: Always appended at the end after the last word
How to Generate Secure Passphrases
[STEP 1] Choose Word Count
Select 4-5 words for general use, 6-7 for important accounts, 8+ for maximum security.
[STEP 1] Select Separator
Choose a separator character or use spaces. Hyphens are commonly accepted.
[STEP 1] Generate & Copy
Click generate, then copy your passphrase or export multiple passphrases.
Passphrase Security Best Practices
- _ Use at least 4 words for basic security, 5+ for important accounts
- _ Memorize your master passphrase, never write it down
- _ Use unique passphrases for different accounts
- _ Consider adding personal modifications you can remember
- _ Store passphrases in a secure password manager for convenience
Technical Implementation
Our passphrase generator implements the Diceware method using the EFF Large Wordlist containing 7,776 carefully selected English words. The system generates cryptographically secure random indices to select words with uniform probability distribution, ensuring each passphrase maintains predictable entropy levels.
// Mathematical entropy calculation entropy = word_count × log₂(wordlist_size) // EFF Large Wordlist: 7,776 words = 5 dice rolls (6⁵) entropy_per_word = log₂(7776) ≈ 12.925 bits // Example: 5-word passphrase 5 × 12.925 ≈ 64.6 bits of entropy
