Password Generator 16 Characters

  • Browser-based
  • No signup

This 16-character password generator produces fixed-length random strings with uppercase, lowercase, numbers, and optional symbols. Sixteen characters satisfies many banking and enterprise policies while staying copy-friendly—generated locally.

Sixteen characters is a common policy minimum. Increase length when the service allows—every extra character raises crack cost.

Exclude ambiguous characters if you must read passwords aloud or type on mobile.

100% Client-Side

Your data never leaves your computer.

How to use this tool
