Made in your browser with its cryptographic random generator. Never sent or saved.

What is a password generator?

A strong password is long and random. Each extra character multiplies the number of possible passwords, so 16 random characters from letters, numbers and symbols give over 100 bits of randomness, far beyond what guessing attacks can reach.

Features

  • 6 to 64 characters
  • Choose capitals, small letters, numbers and symbols
  • Option to leave out look-alike characters
  • Strength shown in bits
  • crypto.getRandomValues, unbiased

How to use the password generator

  1. Set the length; 16 or more is a good default.
  2. Choose the character types the site allows.
  3. Copy the password into your password manager.

Good password habits

  • Use a different password for every account.
  • Store them in a password manager rather than a notebook or a file.
  • Turn on two-step verification for email, banking and UPI apps.
