Password Generator

A secure password generator uses cryptographically secure pseudorandom algorithms to create passwords with high entropy. Our tool combines your selected character sets with true randomness to generate passwords that are statistically unpredictable and resistant to brute force attacks. Each character is independently selected from the available character pool, ensuring maximum security.

A strong password combines length, character variety, and true randomness. Passwords with at least 12 characters including uppercase, lowercase, numbers, and symbols achieve high entropy levels. Our strength analysis evaluates length, character diversity, and pattern absence to provide accurate security ratings ranging from Very Weak to Very Strong.

Excluding ambiguous characters like 0, O, 1, l, and I can improve password readability when typing manually. This option is useful for passwords that will be transcribed or communicated verbally. However, including all characters provides higher entropy. Choose based on your specific use case and communication requirements.

For optimal security, passwords should be at least 12 characters long. Higher-security applications like encryption keys or administrative accounts benefit from 16 or more characters. Our tool supports passwords up to 128 characters, allowing you to meet any security requirement while maintaining strong entropy levels.

Our password generator operates entirely in your browser with no server transmission or storage. All generation happens client-side using your device’s secure random number generator. Generated passwords never leave your browser, ensuring complete privacy and eliminating any risk of interception or logging.

Yes, our tool supports bulk generation of up to 50 passwords simultaneously with consistent security parameters. This feature is ideal for provisioning multiple user accounts, rotating credentials across systems, or creating test data. All generated passwords maintain the same character set and length specifications you configure.

Entropy measures the unpredictability of a password in bits. Higher entropy means more possible combinations, making brute force attacks exponentially harder. Our tool calculates entropy based on character set size and password length. A password with 80 bits of entropy or higher is considered very strong and resistant to modern attack methods.

Including symbols significantly increases password entropy by expanding the available character set. However, some systems have symbol restrictions or compatibility issues. Our tool allows you to enable or disable symbols based on your specific requirements, ensuring generated passwords work with your target system’s validation rules.

Our export feature creates local files directly in your browser with no server interaction. Choose between plain text for simple copying or CSV format for structured data with metadata. Always store exported password files in encrypted storage solutions or secure password managers rather than plain text documents.

Ambiguous characters include 0, O, 1, l, and I which look similar in many fonts. Similar characters expand this to include 5, S, 2, and Z which can also be confused. Excluding ambiguous characters helps with manual transcription, while excluding similar characters is stricter and useful when passwords must be communicated across different display systems.
