FAQs
Is this password generator secure?
Yes, this password generator is highly secure because the entire generation process runs locally within your web browser using JavaScript. The generated passwords are never transmitted over the internet, stored on a server, or logged. This ensures complete privacy and security for your generated credentials.
How do I use the password generator?
To begin, select the desired generation type: Random Password, Passphrase, or PIN Only. Next, adjust the length using the slider, which ranges from 10 to 100 characters for random passwords to 3 to 8 words for passphrases. For Random Passwords, customize the character set using the toggle options for Numbers, Symbols, and Case. Finally, click Generate Password and then Copy Password to securely save the result.
What are "Ambiguous Characters" and why should I avoid them?
Ambiguous characters are letters and numbers that look extremely similar, such as the number one (1), the lowercase letter L (l), and the uppercase letter I (I). Avoiding them is recommended if you frequently need to transcribe the password by hand from a screen to a keyboard. Excluding these characters prevents common entry errors, improving usability without significantly compromising security.
What is 'Entropy' and what does the 'Strength' score mean?
Entropy is a measure of the randomness and unpredictability of your password, expressed in bits. A higher bit score indicates an exponentially larger number of possible passwords, making it significantly harder for an attacker to guess or crack. The Strength indicator translates this score into a clear rating (Weak, Fair, Strong, Excellent) to help you quickly assess its resilience against brute-force attacks.
Why do the customization options (Numbers, Symbols, Case) get grayed out for PIN and Passphrase?
These character customization options are only applicable to the Random Password type. The PIN type is strictly limited to numbers, meaning other characters are irrelevant. Similarly, the Passphrase uses a fixed dictionary of words and a separator, making the individual symbol and case toggles redundant for word-based generation.
What is the difference between a Random Password, a Passphrase, and a PIN?
A Random Password is a complex string of diverse characters, offering maximum digital security but is difficult to remember (e.g., 5y@k9P!wF). A Passphrase is a sequence of random words joined by a separator, making it strong yet much easier for a person to recall (e.g., Sunrise-Coffee-Rocket). A PIN Only is a numerical sequence intended only for quick, low-security access where complexity is not a primary requirement.
