Is this password generator safe to use?

Yes. All passwords are generated entirely in your browser using the Web Crypto API (crypto.getRandomValues). No data is sent to any server. You can verify this by checking your browser's Network tab — there are zero outgoing requests.

How long should a strong password be?

A minimum of 16 characters with uppercase, lowercase, numbers, and symbols gives about 100 bits of entropy — effectively uncrackable. For critical accounts, use 24+ characters.

Does this password generator store my passwords?

No. Passwords are never stored on any server. The optional history feature uses sessionStorage only, which is automatically cleared when you close your browser tab.

What makes a password cryptographically secure?

A cryptographically secure password uses true randomness from a CSPRNG (Cryptographically Secure Pseudo-Random Number Generator), is long enough to have high entropy, and avoids predictable patterns. SecurePass uses crypto.getRandomValues() — the same API used by professional security tools.

Can I use this password generator offline?

Yes! SecurePass works completely offline. Once the page is loaded, it requires no internet connection to generate passwords. It also includes a PWA manifest so you can install it on your device.

Password Generator vs Password Manager

People often confuse password generators and password managers — or assume they serve the same purpose. In reality, they're complementary tools that solve different problems. Understanding both will dramatically improve your online security.

What Is a Password Generator?

A password generator creates random strings of characters to be used as passwords. A good generator:

Uses cryptographic randomness (not Math.random())
Lets you control length and character types
Runs locally — no data sent to servers
Is a one-time-use tool: you generate, copy, and go

What it doesn't do: store passwords, autofill, sync across devices, or remember which site uses which password.

What Is a Password Manager?

A password manager is a secure vault that:

Stores all your passwords in encrypted form
Autofills credentials on websites and apps
Syncs across all your devices
Often includes a built-in password generator
Can detect reused or leaked passwords

What it doesn't do: generate standalone passwords independently of its interface (making it awkward for one-off uses, guest computers, etc.)

Which Do You Actually Need?

The honest answer: both, used together. Here's the ideal workflow:

Go to SecurePass (or any trusted standalone generator)
Generate a 20-character random password
Copy it into your password manager when registering for a new account
Let the password manager save and autofill it from then on

This gives you the best of both worlds: cryptographically secure generation + convenient storage and autofill.

Best Free Password Managers in 2025

Bitwarden — Open source, free tier is excellent, cross-platform
KeePassXC — Fully offline, open source, stores vault locally
Proton Pass — Privacy-focused, made by Proton (same team as ProtonMail)

When to Use a Standalone Generator

There are specific situations where a standalone generator is better than using your password manager's built-in generator:

You're on someone else's computer and your manager isn't installed
You need a password for a system that isn't a website (server, WiFi, encrypted drive)
You want to generate passwords in bulk for a team
You want to verify what a "secure" password actually looks like

Bottom Line

Think of a password generator as a factory and a password manager as a warehouse. You need the factory to produce good goods (strong passwords) and the warehouse to store and ship them (autofill). Use both — they're free.
