What is a Password Generator?

A password generator creates random strings that are hard to guess. You choose length and which kinds of characters to include, then copy the result into your password manager or account form.

How to Generate Strong Passwords

Use at least 12–16 characters for important accounts.
Mix uppercase, lowercase, numbers, and symbols.
Avoid personal words, dates, or keyboard patterns.
Store passwords in a reputable password manager.

Why Strong Passwords Matter

Weak or reused passwords are a common way accounts get taken over. Long, random passwords reduce the risk of brute-force and guessing attacks.
