About Password Generator
Weak and reused passwords are the most common way accounts get hacked. A random password generator creates passwords that are hard to guess and impossible to predict from personal information.
Choose the length and character types, exclude look-alike characters if you need to type the password, and copy the result. Passwords are generated in your browser using a cryptographically secure random number generator and are never sent to our servers.
When to use it
- Creating passwords for new accounts.
- Replacing weak or reused passwords after a data breach.
- Setting Wi-Fi and router passwords.
- Generating temporary passwords for new users.
Tips for better results
- Use a unique password for every account — a password manager makes this easy.
- Turn on two-factor authentication for email, banking and social media.
- Use at least 12–16 characters; longer is stronger.
How to use the Password Generator
- Set the length and pick which character types to include.
- Optionally exclude look-alike characters such as I, l, 1, O and 0.
- Copy your password, or press Regenerate for a new one.
Frequently asked questions
Are these passwords really random?
Yes. They are generated with your browser's cryptographically secure random number generator (the Web Crypto API), using unbiased selection so every character is equally likely.
Do you store or see my passwords?
No. Passwords are created on your device and exist only on this page. Nothing is uploaded, logged or saved — reloading the page erases them.
How long should my password be?
Use at least 12–16 characters with all character types for everyday accounts, and a password manager so every account has a unique password.
How is strength calculated?
Strength is based on entropy — the number of possible passwords with your settings. The crack-time estimate assumes an attacker trying one trillion guesses per second.
How do I remember random passwords?
Use a password manager such as Bitwarden, 1Password or your browser’s built-in manager. It stores your passwords securely so you only need to remember one strong master password.
Should I change my passwords regularly?
Modern guidance says change a password when there is a reason — such as a breach or suspected compromise — rather than on a fixed schedule. Long, unique passwords are more important than frequent changes.
