How to create a strong password?

Our generator uses cryptographically strong browser algorithms (Web Crypto API) to create truly random passwords.

  1. Select length: The recommended length for modern security standards is at least 12-16 characters.
  2. Configure characters:
    • Enable Special characters (!@#) and Numbers for maximum complexity.
    • Use the "Easy to read" option if you need to enter the password manually (excludes similar characters like l, 1, and I).
  3. Generate: Click the button and copy the result. The progress bar will show how hack-resistant your password is.

Security: All passwords are generated directly in your browser. We never see, store, or transmit your passwords to the server.

How to generate a random string in code

Examples of how developers generate random tokens or passwords in different programming languages.

JavaScriptWeb Crypto API

const length = 16;
const charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*";
let retVal = "";
const values = new Uint32Array(length);

// Safe generation
crypto.getRandomValues(values);

for (let i = 0; i < length; i++) {
  retVal += charset[values[i] % charset.length];
}
console.log(retVal);
Pythonsecrets module

import secrets
import string

alphabet = string.ascii_letters + string.digits + string.punctuation
password = ''.join(secrets.choice(alphabet) for i in range(16))

print(password)
# Output: K9@s#l2!mP1$qW5^
PHPrandom_bytes

// Generates cryptographically strong bytes and converts them to hex
$bytes = random_bytes(8); // 16 characters in hex
echo bin2hex($bytes);

// Or base64 for higher density
echo base64_encode(random_bytes(12));
Go (Golang)crypto/rand

package main

import (
    "crypto/rand"
    "encoding/base64"
    "fmt"
)

func main() {
    b := make([]byte, 16) // 16 Π±Π°ΠΉΡ‚
    rand.Read(b)
    fmt.Println(base64.URLEncoding.EncodeToString(b))
}

Why use a password generator?

  • Account Registration: Never use the same password twice. Generate a unique, complex password for each service.
  • API Keys & Secrets: When developing applications, you often need secret keys for configuration (e.g., JWT_SECRET or encryption keys).
  • Temporary Access: If you need to share Wi-Fi access or a temporary account with a colleague, create a password that is impossible to guess.

Frequently Asked Questions (FAQ)

How secure is this generator?

Completely secure. All logic is executed on your device (client-side). We use the window.crypto API, which provides the same degree of randomness as professional cryptographic systems.

How long should a password be?

In 2024, we recommend a minimum of 12 characters for regular accounts and 16+ characters for important ones (banking, email, admin). A 12-character password with numbers and symbols would take 34,000 years to crack using brute-force.
