Password Generator — Free
Create strong, secure passwords with custom length and character sets. Uses cryptographic randomness.
Cryptographic random
Uses the Web Crypto API — the same randomness as your OS provides.
Fully customizable
Mix uppercase, lowercase, digits, and symbols as needed.
Fully private
Generated locally in your browser. Passwords never leave your device.
What is a password generator?
A password generator creates random, unpredictable passwords that are far harder to guess or crack than anything a human would come up with — including passwords built from real words, birthdates, or predictable substitutions like "P@ssw0rd". Pixvert's password generator uses the Web Crypto API, the same cryptographically secure randomness browsers rely on for encryption, instead of a weaker pseudo-random function.
You control the length and which character sets are included — lowercase, uppercase, numbers, and symbols — so you can match the requirements of any login form, from a simple 8-character minimum to a 64-character passphrase for a password manager. A live strength indicator shows how resistant the result is to brute-force attacks.
Reusing or reusing variations of the same password across sites is one of the most common causes of account breaches: once one service leaks a password, attackers try it everywhere else. Generating a unique, random password per account — ideally stored in a password manager — removes that risk entirely.
How to generate a strong password
- 1
Set the length — longer passwords are exponentially harder to crack — 16+ characters is a solid default
- 2
Choose character sets — toggle lowercase, uppercase, numbers, and symbols depending on what the target login accepts
- 3
Check the strength indicator — confirm the result falls in the strong or very strong range
- 4
Generate in bulk if needed — create multiple passwords at once when setting up several accounts
- 5
Copy and store it — copy the password with one click and save it in a password manager rather than memorizing it
When to use a password generator
New account signups
Generate a unique password every time you create an account instead of reusing an old one.
Password manager master password
Create a long, high-entropy passphrase for the one password you do need to remember.
Shared team credentials
Generate strong temporary passwords for shared logins, Wi-Fi networks, or admin accounts.
Post-breach password resets
Quickly generate new passwords for every account affected after a service reports a data breach.
API keys and secrets
Use as a quick source of random characters for tokens, secrets, or temporary access codes.
Why use Pixvert to generate passwords?
- ✓Cryptographically secure randomness: built on the Web Crypto API, not a predictable pseudo-random generator
- ✓100% local, nothing transmitted: passwords are generated and shown only in your browser — never sent to a server or logged
- ✓Full customization: control length and character sets to match any password policy
- ✓Bulk generation: create several passwords at once for multiple accounts
Frequently Asked Questions
Are these passwords actually random and secure?
Yes. The generator uses the Web Crypto API's cryptographically secure random number generator, the same source browsers use for encryption — not a predictable Math.random() function.
Is my generated password sent anywhere or logged?
No. Everything happens locally in your browser. Pixvert never sees, stores, or transmits the passwords you generate.
What password length should I use?
For most accounts, 16 characters or more with mixed character sets is recommended. For a password manager master password, consider 20+ characters.
Should I include symbols in every password?
Include them when the login form allows it — symbols increase entropy. Some legacy systems restrict special characters, in which case rely on length instead.
How is password strength calculated?
The indicator estimates entropy based on length and the variety of character sets used, giving a rough measure of how many attempts a brute-force attack would need.
Can I generate multiple passwords at once?
Yes, use the bulk generation option to create several passwords in one go, useful when setting up multiple accounts at the same time.
Should I still use a password manager?
Yes. Generating strong unique passwords is only half the solution — a password manager lets you store and autofill them without needing to memorize any of them.
