How to Generate Secure Passwords in 2026 — AllTools

Introduction

Weak passwords remain the leading cause of account breaches. Yet most people still reuse simple passwords across multiple accounts because creating and remembering strong ones feels impossible. Online password generators solve the creation problem, but many send your generated passwords through their servers — defeating the purpose of security. The AllTools Password Generator creates cryptographically secure passwords entirely in your browser using the Web Crypto API. Nothing is transmitted, stored, or logged.

What You’ll Need

A modern web browser. That’s it. No software to install, no account to create, no extension to add. Works on any device — desktop, phone, or tablet.

Step-by-Step Guide

1. Open the Password Generator

Go to the AllTools Password Generator. The tool is ready to use immediately.

2. Choose Your Password Type

Three modes are available:

  • Password — Traditional random character passwords. Best for accounts managed by a password manager where you don’t need to memorize them
  • Passphrase — Random words separated by hyphens (e.g., “timber-rocket-blanket-crystal”). Easier to remember while remaining highly secure
  • PIN — Numeric-only codes for banking apps, device locks, and services that require digits only

3. Customize Your Settings

For passwords:

  • Length — Slide from 8 to 128 characters. 16+ characters is recommended for important accounts
  • Character types — Toggle uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols (!@#$%)
  • Exclusions — Remove similar characters (0/O, 1/l/I) to avoid confusion when reading passwords aloud, or exclude ambiguous symbols

For passphrases:

  • Word count — Select 3 to 10 words. Four words minimum is recommended for good security

For PINs:

  • Choose any length from 4 to 20 digits

4. Generate and Copy

Click generate to create your password. The strength meter shows an instant assessment. Click copy to save it to your clipboard. Use the bulk generation feature to create multiple passwords at once.

5. Store It Safely

Paste the password into your password manager (1Password, Bitwarden, KeePass, etc.). Never store passwords in plain text files, sticky notes, or unencrypted documents.

Why AllTools Is the Best Option

Security tools should practice what they preach. The AllTools Password Generator uses crypto.getRandomValues() — the Web Crypto API built into every modern browser — for true cryptographic randomness. This is fundamentally different from generators using Math.random(), which is predictable and unsuitable for security.

Unlike LastPass’s online generator or Norton’s password tool, AllTools never transmits your passwords over the network. The generation happens in your browser’s JavaScript engine, and the passwords exist only in your device’s memory until you copy them.

There are no usage limits, no daily caps, and no features locked behind a paywall. Generate as many passwords as you need.

Using Passwords Wisely

Generating a strong password is only half the equation. How you store, manage, and rotate passwords determines your actual security.

One password per account

Never reuse passwords across services. When a service is breached (and breaches happen constantly), attackers try the compromised email/password combination on every major platform. This credential stuffing attack works because people reuse passwords. One unique password per account means one breach stays contained.

Store in a password manager

Memorize one strong master password (use a passphrase). Store everything else in a password manager. The AllTools Password Manager stores credentials locally with AES-256 encryption — your vault never leaves your device. For cloud-synced alternatives, Bitwarden (open source) and 1Password are strong options.

Enable two-factor authentication

A strong password plus 2FA is dramatically more secure than a strong password alone. Use the TOTP Generator for time-based one-time passwords, or use hardware keys (YubiKey) for the strongest protection.

Don’t change passwords on a schedule

The old advice to change passwords every 90 days is outdated. NIST now recommends against regular rotation because it leads to weaker passwords (people make predictable changes like Password1 → Password2). Change passwords only when you have reason to believe they’ve been compromised.

FAQ

Are these passwords truly random?

Yes. They use the Web Crypto API (crypto.getRandomValues()), which provides cryptographically secure pseudorandom numbers sourced from your operating system’s entropy pool. This is the same randomness source used by encryption libraries and is fundamentally different from Math.random(), which is predictable.

Is a passphrase more secure than a password?

A 4-word passphrase provides roughly equivalent security to a random 10-character password. Passphrases are better when you need to type the password manually (master passwords, device logins). For accounts managed by a password manager, use maximum-length random passwords since you won’t need to type them.

How long should my password be?

At minimum 12 characters, ideally 16 or more. For critical accounts (email, banking, password manager master password), use 20+ characters or a 5-word passphrase. Length contributes more to security than complexity — a 20-character lowercase password is stronger than an 8-character mixed-case password with symbols.

How often should I change my passwords?

Only when you suspect a compromise — not on a regular schedule. NIST SP 800-63B explicitly recommends against periodic password rotation. Instead, use strong unique passwords and monitor for breaches using services like Have I Been Pwned.

Can someone at AllTools see my generated password?

No. The password is generated entirely in your browser’s JavaScript engine. No network request is made. The password exists only in your browser’s memory and on your clipboard after copying. AllTools has no server component for password generation.
