Uses cryptographically secure randomness
Passwords are generated using window.crypto.getRandomValues, the secure random number generator built into modern browsers.
Cryptographic Randomness
Generate Truly Random Passwords with Browser Cryptography
Strong passwords begin with unpredictable randomness. Encrypti0n generates random passwords locally using your browser's built-in cryptographic random number generator instead of predictable words, keyboard patterns, or dates.

Random Password Generator
Uses cryptographically secure randomness - Fair character selection without statistical bias - Generate, regenerate, and copy passwords instantly
01
Passwords are generated using window.crypto.getRandomValues, the secure random number generator built into modern browsers.
02
Character selection removes modulo bias to ensure every available character has an equal chance of being selected.
03
Generate as many independent passwords as you need with a single click.
Built for trust
Designed to keep things secure
Everything is designed to help you complete the task with as little friction as possible.
Fair character selection without statistical bias

How random password generation works
Every generated password begins with secure random numbers before being converted into readable characters.
Secure randomness
Your browser generates cryptographically secure random bytes.
Character selection
Those random values are fairly mapped to letters, numbers, and symbols without introducing statistical bias.
Password creation
The generated characters become a strong random password ready to use.
Generate again
Every new password is completely independent from the previous one.
What to expect
Helpful information before you begin
- Passwords are generated using window.crypto.getRandomValues, the secure random number generator built into modern browsers.
- Character selection removes modulo bias to ensure every available character has an equal chance of being selected.
- Generate as many independent passwords as you need with a single click.
- Create passwords using the default character set or define your own special characters to satisfy specific password policies.
Good to know
Security and privacy notes
- Even a strong random password should never be reused across multiple accounts or encrypted files.
- Store generated passwords in a trusted password manager instead of relying on memory or unencrypted notes.
Best next step:
Generate a Random Password and keep passwords unique, long, and stored safely.
Real-world use cases
Where Random Password Generator fits into everyday workflows
Security works best when it supports the task people are already trying to complete.
Creating passwords for online accounts
Generate a long unique password, then save it in a trusted password manager before using it.
Generating passwords for encrypted files and messages
Create high-entropy passwords for encryption workflows where guessing resistance matters.
Creating temporary credentials
Generate short-lived secrets for access handoffs and replace them when the task is complete.
Importing secure passwords into password managers
Generate the password locally, then store it immediately in a trusted password manager.

Randomness is what makes a password difficult to guess
Many weak passwords look complicated but still follow predictable patterns such as names, dates, or keyboard sequences. Truly random passwords remove those patterns by relying on cryptographically secure randomness instead of human creativity. The result is a password that is dramatically harder for attackers to predict or brute-force.

FAQ
Questions people ask before using this
Encrypti0n uses window.crypto.getRandomValues to generate cryptographically secure random numbers instead of relying on predictable pseudo-random algorithms.
Yes. You can generate passwords using symbols and even customise the special character set to meet website or organisational password requirements.
Yes. Simply generate another password whenever you need one. Every password is created independently using fresh cryptographic randomness.
For most online accounts and password-based encryption, a long random password provides much greater resistance against guessing and brute-force attacks than predictable words or personal information.
Usually not. Strong random passwords are intentionally difficult to remember, which is why a trusted password manager is the recommended place to store them.
Yes. After generating a password, you can open Password Intelligence to analyse its strength, identify potential weaknesses, and estimate its resistance against different attack scenarios.
No. Strong passwords are an important foundation, but good security also includes unique passwords, multi-factor authentication where available, secure devices, and protection against phishing.
