पासवर्ड जनरेटर
Strong password generator
A truly random password in one tap. It is made in this tab and never stored, logged or sent anywhere.

Press the button to make a password. It is created in this tab and never leaves it.
Strength
Very strong
Entropy
103 bits
Character pool
86
Entropy is length × log2(pool size): the number of bits an attacker would have to guess if they knew your settings. Characters come from crypto.getRandomValues. The password is not stored, logged or sent anywhere, and it disappears when you close the tab. Use a different password for every account and keep them in a password manager.
How to use it
- 01Set the length and the kinds of characters.
- 02Press Generate password.
- 03Copy it straight into your password manager or the sign-up form.
16 characters, all types

About this tool
People are bad at inventing random passwords: we pick names, dates and patterns that attackers guess first. This generator makes passwords from 4 to 128 characters using your browser’s cryptographic random generator (crypto.getRandomValues), so every character is independent and unpredictable. Choose lowercase, uppercase, numbers and symbols, and optionally skip look-alikes such as I, l, 1, O and 0.
The strength readout shows entropy in bits, calculated as length × log2(pool size). Around 70 bits is strong for most accounts and 100 or more is very strong. Length helps more than symbols: a 20-character password with letters and digits beats an 8-character one with symbols.
The password is created in this tab. It is not saved, not logged, not sent over the network and not shared with analytics, and it vanishes when you close the page. Use a different password for every account and keep them in a password manager; turn on two-step verification where you can.
हिंदी में मदद
यह टूल आपके ब्राउज़र के क्रिप्टोग्राफ़िक रैंडम जनरेटर से मज़बूत पासवर्ड बनाता है। लंबाई, अक्षर, अंक और चिह्न चुनें और एंट्रॉपी देखें। पासवर्ड कहीं सेव या भेजा नहीं जाता और टैब बंद करते ही गायब हो जाता है।
Questions
Is the password sent or stored anywhere?
No. It is generated inside this browser tab, is not stored or sent over the network, and disappears when you close the tab.
How long should my password be?
At least 14 to 16 characters for important accounts. Longer is better, and a manager means you never have to remember it.
What does entropy mean?
It is a measure of how many guesses an attacker would need: length × log2 of the number of possible characters. Each extra bit doubles the guesses.
Is it better than one I make up?
Yes. Random passwords have no pattern to guess. Ones people invent often follow predictable habits such as names, years and substitutions like @ for a.
