Generate strong random passwords with customizable length and character options.
A password generator creates cryptographically random strings of characters using your browser's secure random number generator. Strong passwords combine uppercase, lowercase, numbers, and symbols at 16+ characters.
Formula
Combinations = charset_size ^ lengthcharset_size = number of unique characters available (e.g., 95 for full ASCII)
length = total number of characters in the password
^ = exponentiation — length as the power
Worked Example
16-character password using all character types (95 possible chars)
Did you know? A 16-character password with all character types has more possible combinations than there are atoms in the observable universe (≈10⁸⁰). Increasing length by just one character multiplies the search space by 95×.
