Why use a random password generator?
People are bad at inventing passwords โ we pick names, birthdays and patterns that attackers try first. Apassword generator removes the guesswork: it uses your device's secure random number generator to build passwords nobody could predict. Choose a fully random password for maximum strength, or apassphrase of random words that's easier to remember and type on a phone. Everything happens in your browser; the password never leaves your screen.
How to use it
- Pick Random password or Passphrase.
- Set the length (or number of words) and the character types you need.
- Tap Copy, paste it into the sign-up form, and save it in your password manager.
How password strength is measured
Entropy (bits) = length ร logโ(number of possible characters)
For passphrases: words ร logโ(words in the list), plus a little more for the added number.
Example
A 16-character password using upper and lower case letters, digits and symbols draws from about 80 characters (after removing look-alikes), giving 16 ร logโ(80) โ 101 bits โ far beyond what any attacker can brute-force. A 6-word passphrase from our 686-word list has about 56 bits, and adding a number brings it to about 63 bits: strong, and much easier to remember.
Password safety checklist
- Use a different password for every account.
- Store them in a reputable password manager instead of a notes app.
- Turn on two-factor authentication (2FA) for email, UPI and banking apps.
- Never share OTPs or passwords over a phone call โ banks never ask for them.
