How Password Strength Is Calculated
Entropy (bits) = Password Length Γ logβ(Character Set Size) Combinations = Character Set Size ^ Password LengthCalculation Components
- Character Set Size: The total number of unique characters available. Uppercase adds 26, lowercase adds 26, numbers add 10, and symbols add 32 characters to the pool.
- Password Length: The number of characters in your password. Each additional character exponentially increases the total possible combinations.
- Entropy (bits): A measure of randomness. Higher entropy means more possible combinations and a stronger password. 80+ bits is considered very strong.
- Brute Force Time: The estimated time to try every possible combination. Modern computers can try billions of combinations per second, but high entropy makes cracking practically impossible.
- Ambiguous Characters: When excluded, characters like 0, O, o, l, 1, I are removed from the character set, slightly reducing entropy but improving readability.
For example, if Rahul creates a 16-character password using all four character types (94 possible characters), the entropy would be approximately 16 Γ 6.55 = 104.86 bits. This means there are roughly 94^16 β 3.7 Γ 10^31 possible combinations β a number so large that even the fastest supercomputers would need billions of years to try every possibility. This is why using all character types with a good length is recommended for securing important accounts like bank logins, email accounts, and social media profiles in India and worldwide.

Use Case: Onboarding employees, setting up temporary access, or creating initial passwords for team tools.
What Is a Random Password Generator?
A random password generator is a specialized tool that creates passwords using cryptographically secure random number generation, ensuring each password is truly unpredictable and impossible to guess. Unlike human-created passwords that often follow recognizable patterns β using names, birthdays, dictionary words, or common sequences like "123456" β a random password generator produces strings of characters with maximum randomness and entropy.
This free online random password generator from StoreDropship is designed for everyone who values online security, from individual users protecting their personal email and social media accounts to IT professionals managing enterprise-level security. Whether you are setting up a new bank account password, securing your government portal access like DigiLocker or UMANG, or creating credentials for your e-commerce business, this tool delivers professional-grade password generation right in your browser.
The tool is built using the Web Crypto API, the same cryptographic standard used by password managers and security applications worldwide. It supports customizable lengths from 4 to 128 characters, four character types (uppercase, lowercase, numbers, symbols), bulk generation of up to 50 passwords, and an option to exclude visually ambiguous characters. Every password is generated entirely on your device with zero data transmission, making it one of the most private and secure password tools available online. Our password strength indicator provides real-time feedback using entropy calculations, helping you understand exactly how secure your generated password is against modern brute-force attacks.
Frequently Asked Questions
Yes, this Random Password Generator is 100% completely free to use with no hidden charges, no subscription fees, and no premium upgrades required. You can generate unlimited passwords of any length and complexity without creating an account or paying anything. StoreDropship provides this tool as a free service to help everyone create strong, secure passwords for their online safety.
Absolutely. Your data is completely safe and private. This Random Password Generator runs entirely in your web browser using client-side JavaScript. No passwords are ever sent to any server, stored in any database, or transmitted over the internet. The passwords are generated using the Web Crypto API directly on your device. Once you close or refresh the page, all generated passwords are permanently gone from memory. We have zero access to any password you generate.
This password generator uses the Web Crypto API (crypto.getRandomValues), which is a cryptographically secure pseudo-random number generator built into modern browsers. This is the same technology used by professional security applications and password managers. The randomness quality is extremely high, making the generated passwords virtually impossible to predict. Each character is independently and uniformly selected from your chosen character set.
A strong password is at least 12-16 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. The longer and more complex your password, the harder it is to crack. A 12-character password with all character types would take millions of years to crack through brute force. For highly sensitive accounts like banking or email, we recommend using 16 or more characters with all four character types enabled.
Yes, you can generate up to 50 passwords at once using the quantity selector. This is particularly useful when you need to create passwords for multiple accounts, set up passwords for team members, or want several options to choose from. Each password is independently generated with full randomness, and you can copy any individual password with a single click on the copy button next to it.
The Exclude Ambiguous Characters option removes characters that look similar to each other, such as 0 (zero) and O (letter O), 1 (one) and l (lowercase L) and I (uppercase i). This is helpful when you need to read, share, or type passwords manually, as these similar-looking characters can cause confusion and login errors. Enable this option if you plan to write down or verbally communicate your password.
Humans are predictable when creating passwords. We tend to use dictionary words, personal information like birthdays and names, common patterns like 123456, and simple substitutions like @ for a. Hackers know these patterns and use them in attacks. A random password generator creates truly unpredictable passwords using cryptographic randomness, making them exponentially harder to crack through dictionary attacks, brute force, or social engineering.
Yes, this Random Password Generator is fully responsive and works perfectly on all devices including smartphones, tablets, laptops, and desktop computers. The interface automatically adjusts to your screen size for the best user experience. It works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera on both Android and iOS devices. No app installation is required.
The password strength indicator evaluates your password based on multiple factors: length, character variety (uppercase, lowercase, numbers, symbols), and overall entropy. Entropy measures the total number of possible combinations a hacker would need to try. The strength meter shows ratings from Very Weak to Very Strong with corresponding colors. A password is considered strong when it has high entropy, which comes from using longer lengths and more character types.
No, hackers cannot intercept passwords generated by this tool because the entire generation process happens locally in your browser. No data is transmitted over the internet, so there is nothing to intercept. The passwords exist only in your browser's memory and on your screen. However, we recommend using the password immediately and not saving it in an unencrypted file. For storing passwords safely, consider using a reputable password manager application.
When you enable the Symbols option, the generator includes these special characters: ! @ # $ % ^ & * ( ) _ + - = [ ] { } | ; : ' , . < > ? / ~ `. These are commonly accepted by most websites and applications. If a specific website restricts certain symbols, you can generate a new password or manually adjust the generated one. The wide variety of symbols significantly increases password strength.
Modern security guidelines from NIST (National Institute of Standards and Technology) suggest changing passwords only when there is evidence of a breach rather than on a fixed schedule. However, you should immediately change your password if you suspect unauthorized access, if a service reports a data breach, or if you have shared your password with someone. Using unique, strong passwords for each account and enabling two-factor authentication provides better security than frequent password changes.
There is no overall limit on how many passwords you can generate. You can use this tool as many times as you want, completely free of charge. Each session allows generating up to 50 passwords at once, and you can click the generate button repeatedly to create new sets. Since everything runs in your browser, there are no server limitations, rate limits, or usage quotas of any kind.
