Passwords
Password Generator
Create strong, random passwords with custom requirements like symbols and numbers.
Longer passwords dramatically increase brute-force search space. Aim for 16+ characters with mixed symbols.
Generation runs only in your browser using the Web Crypto API. Nothing is sent over the network.

Strength assumes random selection from the detected character sets. Avoid reused phrases to resist dictionary attacks.
About Password Generator
This Password Generator creates high-entropy credentials to secure your accounts. It builds a strong password by combining uppercase letters, numbers, and symbols, ensuring resilience against dictionary and brute force attacks.
Protect your digital identity with a robust password strength strategy. Reusing simple passwords allows attackers to compromise multiple accounts easily. Generating a unique, complex password for every service is the most effective defense against credential stuffing.
Customize the length and character sets (A-Z, 0-9, Symbols). As you adjust settings, the tool provides real-time feedback on the crack time and security score. Copy the secure string to your password manager immediately.
Under the Hood
Password strength is evaluated using zxcvbn-inspired logic, specifically checking for common patterns and calculating entropy bits. The actual generation involves a Crypto Random (CSPRNG) byte stream mapped to the selected character sets. Entropy estimates help visualize complexity, where >60 bits generally resists online attacks and >128 bits resists offline brute force attacks using current hardware.
