Password Generator
Generate cryptographically secure random passwords of any length. Choose from letters, numbers, symbols and more.
About the Password Generator
A password generator creates random passwords so you do not have to invent them. Humans are poor at randomness: we choose names, dates and predictable substitutions like replacing a with @, and attackers know these tricks. Random passwords avoid that weakness.
Length matters more than complexity. A random 16 character password drawn from upper case, lower case, numbers and symbols has about 105 bits of entropy, far beyond brute-force guessing. A random 12 character password using letters and numbers has about 71 bits, still strong for most uses.
Use a different password for every account so a leak at one site does not expose the others, store them in a reputable password manager, and turn on two-factor authentication wherever available.
Setting the length to 20 with all character types selected produces a random string of mixed letters, numbers and symbols with roughly 119 bits of entropy.
Tips for best results
- Choose at least 14 to 16 characters for important accounts such as email and banking.
- If a site rejects certain symbols, turn symbols off and increase the length instead.
