Strong Password Generator
Create secure passwords with real-time strength analysis, entropy estimation, and presets.
How to Use
Set Your Length
Choose how long you want your password to be. A length of 12-16 characters is generally recommended for high security.
Choose Characters
Toggle between uppercase, lowercase, numbers, and symbols to meet specific security requirements or website constraints.
Use Quick Presets
Click a preset like 'Easy to Read' or 'Maximum' to instantly apply pre-configured settings. Presets are great for common use cases like creating memorable or ultra-secure passwords.
Apply Restrictions
Enable options like 'No consecutive repeat', 'No sequences', or 'No keyboard patterns' to block weak patterns such as 'aaa', '123', or 'qwerty' from appearing in your password.
Generate in Bulk
Set the quantity above 1 to generate multiple passwords at once. This is useful when you need unique passwords for several accounts in one go.
Export Your Passwords
Use the export dropdown to download your generated passwords as TXT, CSV, or JSON. Great for storing securely in a password manager.
Generate and Copy
The password updates instantly as you change settings. Click the copy button to save it to your clipboard for immediate use.
Frequently Asked Questions
What makes a password truly secure?
A secure password is long (12+ characters), uses a mix of character types (letters, numbers, symbols), and is unique—never reused across different accounts. Our generator helps you achieve all three effortlessly.
Is it safe to generate passwords online?
Yes, when using our tool. The generation happens entirely in your browser using JavaScript. No password data is ever sent to our servers or stored anywhere, ensuring 100% privacy.
What is entropy in passwords?
Entropy is a measure of randomness. The higher the entropy (measured in bits), the harder it is for a computer to guess your password through brute-force attacks.
What is the difference between the presets?
'All Characters' uses everything for maximum security. 'Easy to Read' excludes ambiguous characters like Il1O0. 'Easy to Say' avoids symbols and digits for simpler verbal sharing. 'Maximum' pushes length to 32 characters. 'PIN' generates a numeric-only code.
How is the strength score calculated?
The strength score (0–100) combines password length, character diversity, and entropy. A score of 80+ is considered strong, 60–79 is moderate, and below 60 is weak. The crack time estimate assumes a billion guesses per second.
What are keyboard patterns and why avoid them?
Keyboard patterns like 'qwerty', 'asdf', or 'zxcvbn' are common sequences on a QWERTY keyboard. Hackers include these in their dictionaries because people often use them as shortcuts, making passwords significantly weaker.
How many passwords should I generate at once?
You can generate up to 100 passwords at a time. This is ideal for creating unique passwords for all your accounts in a single session. Store them securely—preferably in a password manager.
What characters can I exclude and why?
You can exclude any characters you don't want in your password, such as @ # $ %. Some websites restrict certain special characters, and this field lets you comply without sacrificing security.
