Password Generator

What is Password Generator?

This tool automatically generates multiple strong and secure passwords simultaneously. You can customize password characteristics such as length and character types (numbers, letters, symbols) based on your security requirements. Generated passwords can be batch-copied or downloaded as a CSV file, making it convenient when setting up multiple accounts.

Problems This Tool Solves

• Reducing security risks: Prevents the use of weak, easily guessable passwords
• Streamlining password management: Generate multiple passwords at once when creating new accounts across different services
• Meeting security policy requirements: Create passwords that comply with corporate or organizational password requirements (length, complexity)
• Improving system administrator efficiency: Save time when creating large numbers of test or user accounts
• Eliminating human-created security weaknesses: Generate truly random passwords that avoid predictable patterns humans tend to create

How to Use

1. Set character types: Select which character types to include (numbers, lowercase/uppercase letters, symbols) using checkboxes
2. Configure strength: Set password length using the slider and enable the "Include at least one of each character type" option if needed
3. Specify quantity: Set the number of passwords (1-100) you need
4. Click the Generate Password button
5. Copy or Download as CSV the generated passwords

Password Configuration Options

Character Type Settings

Include Numbers

When checked, passwords will include digits from 0-9. Adding numbers increases password strength compared to purely alphabetical passwords.

Include Lowercase Alphabets

When checked, passwords will include lowercase letters from a-z. Many password policies require at least one lowercase letter.

Include Uppercase Alphabets

When checked, passwords will include uppercase letters from A-Z. Adding uppercase letters increases password complexity and security level.

Include Symbols

When checked, passwords will include special characters (such as !@#$%^&*()-_=+[]{}|;:,.<>?/). Adding symbols significantly increases the difficulty of cracking passwords.

Exclude Ambiguous Characters

When checked, visually confusing characters (e.g., oO0 - lowercase o, uppercase O, and zero) won't coexist in the same password. This prevents confusion when manually typing passwords.

Password Strength Settings

Specify Length

Use the slider to set the character count for your passwords, ranging from 8 to 32 characters. Default is 8 characters.

Password length directly impacts security:

• 8-10 characters: Basic protection (suitable for general personal accounts)
• 12-16 characters: Strong protection (recommended for important services and financial accounts)
• 16+ characters: Maximum protection (ideal for administrator access and critical corporate data)

Include at Least One of Each Character Type

When checked, each generated password will contain at least one character from each selected type (number, lowercase, uppercase, symbol). Many organizational and service password policies require this, making passwords generated with this option widely compatible.

Password Quantity

You can specify how many passwords to generate at once, from 1 to 100. Default is 20 passwords. This is useful when setting up multiple accounts simultaneously or when you want to compare several password options.

Utilizing Generated Passwords

Copy Functions

• Batch copy: Copy all generated passwords to your clipboard for pasting where needed
• Individual copy: Select and copy specific passwords individually

CSV Download

Download the list of generated passwords as a CSV file, which enables:

• Bulk import into password management software
• Batch user registration in corporate systems
• Secure storage of passwords in a structured format

Security Best Practices

Recommendations for maximizing the effectiveness of strong passwords generated with this tool:

• Use passwords of at least 12 characters for important services
• Never reuse the same password across multiple services
• Store passwords securely with a password manager
• Establish a routine for regular password updates
• Combine with two-factor authentication for enhanced security

Technical Background

This password generator uses a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) to create unpredictable, truly random passwords. It leverages the browser's WebCrypto API to ensure high entropy (randomness), creating passwords resistant to pattern analysis and dictionary attacks.
