How the math works Choose a Length (4 to 64 characters) and whether to Include symbols. Each character is picked at random from 62 letters and digits, or 80 with symbols such as ! @ # and %. Strength in bits = length × log₂(characters to choose from); every extra bit doubles the number of guesses an attacker would need. A new password is made each time you press Calculate. The formula: Possible passwords = (characters to choose from)^length. Strength in bits = length × log₂(characters to choose from). More length helps most.
