Online Password Generator
Cryptographically Strong Online Password Generator
The free online password generator creates cryptographically strong combinations directly in your browser. Generation uses Crypto.getRandomValues() — a cryptographically secure source of randomness. No character is sent to the server: all calculations are performed locally, on the client side.
The tool supports 8 types of passwords — from numeric PIN codes to multi-character combinations with maximum entropy. Length: from 4 to 100 characters. For the passphrase method, word and phrase generation from real books and dictionaries is available.
Why This Is Secure
- Browser cryptographically secure API — true randomness, not a pseudo-generator
- Zero-knowledge: passwords never leave your device
- 94 characters in the pool for complex and random passwords
- Length from 4 to 100 characters, up to 10 words in a phrase
- Clickable chips for copying each variant
- Export formats: string, comma-separated, tab-separated
How It Works
Create a Password in Four Steps
The interface is designed so you can create a strong password in seconds without reading instructions.
01
Choose a Type
Numeric, alphabetic, complex, random, memorable, words, phrases, or multi-character. Each type is designed for its own scenario.
02
Configure Parameters
Set the password length (4–100 characters) and number of variants (up to 100). Enable the options you need: letter case, digits, special characters, spaces.
03
Generate
Click "Create Password" — instant generation on your device. No server requests, no logs. The result appears immediately.
04
Copy and Use
Each variant is a clickable chip. Select the output format and copy with one click. Import into your password manager via comma or tab separation.
Password Types
Eight Password Generation Modes
Each mode solves a specific task — from creating a PIN code to generating corporate credentials.
Numeric
Digits 0–9 only. For PIN codes, door locks, temporary access codes, and systems that only allow digits.
Alphabetic
Latin letters without digits or special characters. Suitable for systems with character set restrictions.
Complex
Uppercase and lowercase letters, digits, special characters. Recommended standard for email, social networks, and cloud services.
Random
Maximum entropy: complete chaos from all available characters. Maximum protection against brute-force attacks for critical systems.
Memorable
Combinations that are easier to remember while maintaining high strength. A balance of security and convenience for everyday accounts.
Words
Random words from real dictionaries. The passphrase is resistant to dictionary attacks. You can choose the number of words in the phrase.
Phrases
Meaningful phrases from real books. High memorability with cryptographic strength. Choose the number of words in the phrase.
Multi-Character
Exact number of characters from each class: digits, letters, special characters. Maximum flexibility for specific security requirements.
Benefits
Why You Should Use This Password Generator
We approach security the same way we protect a backend: zero trust and defense in depth.
Zero-Knowledge Architecture
Generation happens in the browser. The server does not receive or store passwords. Open the Network tab — you will not see a single request during generation. Complete confidentiality.
Measurable Cryptographic Strength
16 characters from a pool of 94 symbols — 94^16 combinations, ~105 bits of entropy. A GPU cluster would need billions of years to brute-force. The entropy of each password is measurable and predictable.
Works Offline
After the page loads, generation works without the internet. All calculations are local, no data is transmitted over the network. Suitable for isolated workstations.
No Limits or Registration
No restrictions on the number of generations, no subscriptions. The tool is free for personal and commercial use. No account creation required.
Frequently Asked Questions
Everything About Creating Secure Passwords
How long should a strong password be?
At least 16 characters. A 16-character password with mixed-case letters, digits, and special characters provides about 105 bits of entropy. For corporate systems, 20+ characters is recommended. When using the passphrase method — 5–6 random words.
Which password type should I choose for different services?
For email, social networks, and cloud services — "Complex." For maximum protection — "Random." For memorable passwords — "Words" or "Phrases" of 5–6 words. For PIN codes — "Numeric." For systems with restrictions — "Alphabetic."
Is it safe to generate passwords online?
Yes, if generation happens on the client side. Our tool does not send data to the server — all calculations are performed in the browser via Crypto.getRandomValues(). You can verify this in developer tools: there will be no network requests during generation.
What is a passphrase?
A passphrase is a sequence of random words, for example "basket helicopter lighthouse glove." It is easier to remember than a character set but provides high strength. Our generator creates phrases from real dictionaries and books — 5 random words yield over 10^20 combinations.
