How long should a password be?

Use case Length Character set Entropy Time to crack

Rows marked * have look-alike characters removed. Crack times assume an offline attacker at 100 billion guesses per second — a realistic GPU rig against a fast hash.

How to use this tool

  1. 1

    Set the length — type it in or drag the slider. 16 characters is a good default; go 20+ for anything that protects money or email.

  2. 2

    Choose the character sets. Turn on No look-alikes when you’ll retype the password by hand, and drop Symbols if the site rejects them.

  3. 3

    Press Generate Password — raise How many to get a batch at once — then Copy Result. Click any password in the list to copy just that one.
