Frequently Asked Questions
How long should a secure password be?
Security guidelines recommend a minimum of 12–16 characters for general accounts and 20+ for high-value targets like email, banking, or work systems. Length is the single biggest factor in password strength — a 20-character lowercase-only password is stronger than a 10-character mixed-type one.
Is this password generator truly random?
Yes. Passwords are generated using the Web Crypto API (window.crypto.getRandomValues), which uses a cryptographically secure pseudorandom number generator (CSPRNG). This is the same standard used by security software and password managers.
Should I store this password in my browser or in a password manager?
A dedicated password manager (Bitwarden, 1Password, Dashlane) is safer than browser-saved passwords. Password managers encrypt your vault with a master key, work across devices, and warn you about reused or compromised passwords. Browser storage is convenient but less secure.
Why should I use a different password for every site?
If one site suffers a data breach and your password is leaked, attackers use automated tools to try that same email and password combination on hundreds of other sites (credential stuffing). Unique passwords per site mean one breach never cascades into account takeovers elsewhere.
Is my generated password sent anywhere?
No. Password generation happens entirely in your browser using JavaScript. Nothing you generate is transmitted to any server, logged, or stored. Close the tab and the password is gone — save it before leaving.
Is the Password Generator free to use?
Yes, the Password Generator on Allio Tools is completely free with no sign-up or registration required. It works directly in your browser.
How does the Password Generator work?
Generate strong, secure random passwords instantly — choose length and character sets (uppercase, lowercase, numbers, symbols). Copy with one click, no account or internet needed. No data is sent to a server — everything runs locally in your browser for maximum privacy and speed.
Do I need to install anything to use the Password Generator?
No installation needed. The Password Generator runs entirely in your web browser on any device — desktop, tablet, or mobile.
Is my data safe when using the Password Generator?
Completely safe. The Password Generator processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
Does the Password Generator work offline?
After the page loads for the first time, the Password Generator works without an internet connection for all client-side processing. Tools that fetch live external data (such as DNS or network lookups) require an active connection.
Are the results from the Password Generator truly random?
Yes. The Password Generator uses your browser's built-in cryptographically seeded random number generator, which provides high-quality unpredictable randomness suitable for games and fair decisions.
Can I customise what the Password Generator generates?
Yes. Where customisation options are available, you can add your own items, set numeric ranges, or adjust parameters before generating. Default settings are designed for the most common use case so you can get an instant result without any configuration.
Does the Password Generator work on all browsers?
Yes. The Password Generator is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
How do I save or export my results from the Password Generator?
Select and copy the result text to paste into any document or app. For image tools, a Download button saves the file directly to your device. Your browser's built-in screenshot function also captures results quickly. No account or login is required.
