Random Password Generator - Create Secure Random Passwords
Generate several random passwords at once. For a single password with a strength rating, use the Password Generator.
What Is a Random Password Generator?
A random password generator creates unpredictable passwords using cryptographically secure random values from your browser. How well a password protects an account still depends on length, character types, uniqueness, and how you store it.
How to Use the Random Password Generator
- Select password length — Choose between 4 and 30 characters.
- Choose how many — Generate 1 to 20 passwords in one click.
- Choose character types — Check or uncheck Uppercase, Lowercase, Numbers, and Symbols. Each generated password includes at least one character from every selected type. Look-alike characters such as 0/O and 1/l/I are omitted from the character pools.
- Click "Generate" — A list of random passwords appears below.
- Click "Copy all" — Copy the list to your clipboard (one password per line).
Password Strength Comparison
Password strength depends on length, randomness, the size of the character set, how the password is stored or hashed, and the attacker’s resources. This tool does not estimate crack time or show a strength score. Longer, random passwords that mix more character types are generally harder to guess than short or predictable ones.
| Password Type | Example | Relative strength |
|---|---|---|
| Short, lowercase only | password | Weaker |
| Medium length, mixed case | PassWord12 | Stronger than lowercase-only of similar length |
| Longer, mixed types | P@ssW0rd!23# | Typically harder to guess than a short mixed-case password |
| Longer still, mixed types | P@$$w0rd!23#AbC$ | Typically harder still, depending on the threat model |
Password Security Tips
- Use at least 12 characters — Longer passwords are exponentially harder to crack
- Include all character types — Mix uppercase, lowercase, numbers, and symbols
- Never reuse passwords — Use unique passwords for each account
- Use a password manager — Store your generated passwords securely
- Enable two-factor authentication — Add an extra layer of security
Why Random Passwords Matter
Short or reused passwords are easier to guess with automated tools. Using a unique, random password of sufficient length, and storing it in a password manager, is a practical way to reduce that risk. Crack time is not a single number: it depends on hashing, hardware, and the attacker’s goals.
Frequently Asked Questions
How secure is this password generator?
This generator uses cryptographically secure random values from your browser’s crypto API. It does not give a strength score, and no generated password is guaranteed unbreakable. Strength still depends on length, selected character types, and how you store and use the password.
Are the generated passwords stored anywhere?
Passwords are generated in your browser. This tool does not intentionally send them to a server. Clipboard managers, browser extensions, or other software on your device are outside this page’s control.
What password length should I use?
We recommend at least 12 characters. For sensitive accounts like banking, use 16+ characters.
Can I use this password generator offline?
Yes, once the page loads, the password generator works offline without an internet connection.
Should I use a password manager?
Yes, we recommend using a password manager like Bitwarden, LastPass, or 1Password to securely store your generated passwords.
