Generate robust, random passwords using this browser-based tool. Set your preferred length from 6 to 99 characters and choose which character types to include—lowercase, uppercase, numbers, and symbols—or input your own custom character set. Generate up to 20 unique passwords at once, each guaranteed to contain at least one character from every selected category. The built-in strength indicator evaluates quality based on length and variety, while the use of `crypto.getRandomValues()` ensures true cryptographic randomness.
This tool generates high-entropy random passwords directly on your device. Customize the length, character sets, and quantity to meet your specific security requirements.
The password count setting allows you to generate between 1 and 20 passwords at a time. This is useful when setting up several new accounts or if you want a list of options to choose from. Every password maintains the same level of randomness regardless of how many you generate at once. For length, we recommend at least 12 characters for standard accounts. Use 16 or more for banking, email, and other sensitive services. While some websites impose character limits, you should always use the maximum length allowed, as extra length provides a significant security boost at no cost.
Toggle the checkboxes for lowercase letters (a-z), uppercase letters (A-Z), numbers (0-9), and symbols (!@#$%^&*). Most modern websites support all four types, and using the full range is highly recommended. The generator ensures at least one character from each selected category appears in every password, preventing rare instances where random selection might skip a required type. Combining all four categories increases the possibilities for each character position to approximately 94, exponentially increasing the total combinations.
Some websites restrict specific symbols or require a very particular set of characters. Enable the custom characters option to define exactly which characters the generator should use. If a site only accepts a handful of symbols (like !@#$), simply enter those characters in the field. The tool will blend your custom input with any other standard types you have selected to ensure the final result remains random yet compliant.
Each password includes a dedicated copy button for quick transfer to your clipboard. The "Copy All" button is useful for moving a batch of passwords into a password manager. Once generated, store your passwords in a secure manager like Bitwarden, 1Password, or your browser's encrypted vault. Never save passwords in plain text files, emails, or notes apps, as these are easily accessed by unauthorized users.
The colored bars below each password provide a visual assessment of security. Passwords under 8 characters or those using only one character type are flagged as weak. Medium-strength passwords generally range from 8–11 characters with mixed types. Passwords with 12–15 characters and multiple types are considered strong, while those with 16+ characters and all four types are rated as very strong. Remember that a shorter password with high character variety is often more secure than a longer one consisting only of lowercase letters.
Banking and financial accounts should use 16–20 characters with all four character types. You should generate a unique password for every institution to prevent a single breach from compromising all your finances. Your primary email account also requires a 16+ character password, as it is often the gatekeeper for password resets on other services. Social media accounts, which contain valuable personal data, should use at least 12–16 characters.
This generator runs entirely in your web browser using the `crypto.getRandomValues()` API. This method draws from your operating system's internal entropy to produce randomness suitable for high-security applications—unlike `Math.random()`, which can be predictable. No data leaves your machine; your passwords are never sent to a server, stored in a database, or recorded in logs. You can verify this by loading the page and then disconnecting your internet—the generator will continue to work perfectly. Once you close the tab, the passwords are wiped from your browser's memory.
Never reuse passwords across different accounts. If one site is compromised, attackers will immediately test those credentials on other popular platforms. Use the passwords exactly as they are generated; manually "tweaking" characters to make them easier to remember significantly reduces the effectiveness of random generation. Finally, always enable two-factor authentication (2FA) where available. Even the strongest password is only one layer of defense; 2FA provides a critical second barrier that blocks attackers even if they obtain your password.
