AES Encryption Explained: How It Works and Why It Matters

Generate random, secure passwords with a mix of lowercase, uppercase, numbers, symbols, and optional separators. Everything runs locally in your browser.
It is also a good idea to use a password manager to help you generate and store strong, unique passwords for all of your accounts. A password manager can also help you keep track of your different passwords and ensure that you are using strong, unique passwords for each account.
A password generator is a tool that creates random, secure passwords based on customizable criteria such as length, character types, and complexity. Instead of relying on memorable words or patterns that attackers can guess, a good password generator uses cryptographically secure randomness to produce passwords that are resistant to brute-force, dictionary, and social engineering attacks.
This password generator runs entirely in your browser using the Web Crypto API (crypto.getRandomValues). Your password never leaves your device — it is not sent over the internet, stored on a server, or logged in any way. The built-in password meter evaluates strength in real time based on entropy, length, character diversity, and uniqueness.
Follow these steps to generate a strong, secure password:
0O1lI. Enable Insert Semicolon (;) and Comma (,) to add separators for readability.Yes. The password is generated locally in your browser using crypto.getRandomValues(), a cryptographically secure random number generator. No data is sent to any server, stored in any database, or logged. Once you close or refresh the page, the generated password is gone.
For most purposes, a password of at least 12 characters is recommended. For sensitive accounts like email, banking, or admin panels, use 16–24 characters. This tool supports up to 128 characters. Longer passwords with mixed character types provide exponentially more combinations and are far more resistant to brute-force attacks.
Weak (red, 0–25%) — Easily guessable; avoid using.
Fair (orange, 26–50%) — Moderate security; suitable for low-risk accounts.
Good (yellow, 51–75%) — Strong security; acceptable for most accounts.
Strong (green, 76–100%) — Maximum security; recommended for sensitive accounts.
Yes, especially if you need to read or type the password manually. This option removes characters like 0 (zero) and O (uppercase o), 1 (one) and l (lowercase L), and I (uppercase i) that are easy to confuse. The trade-off is a slight reduction in the total character pool.
Humans are predictable. Common patterns like capitalizing the first letter, adding a number at the end, or using a ! at the end are well-known to attackers. A random password generator removes all human bias and creates passwords with maximum entropy — meaning each character is equally likely to appear in any position, making the password exponentially harder to crack.
