Generate a Secure Password for Online Accounts

Last updated: February 24, 2026

Every security expert says the same thing: use a unique, strong password for every account. But creating genuinely random passwords is something humans are terrible at — we unconsciously pick patterns, use dictionary words, and reuse variations of the same base password. OneClickPDF's generator uses your device's cryptographic random number generator to create passwords that are truly unpredictable.

The Problem

You're creating a new account — banking, email, work — and need a genuinely strong, unique password. You know 'Winter2026!' isn't good enough, but you can't think of something truly random. You also don't want to type your new password into some website that might log it.

How It Works

Open the Password Generator

Go to OneClickPDF's Password Generator.

Generate a random password

A strong 16-character password is generated immediately using cryptographic randomness. Adjust length and character sets as needed for the site's requirements.

Check the strength

The strength meter shows the password's rating and estimated crack time. Aim for 'Strong' or 'Very Strong' — anything that would take years or longer to crack.

Copy and save

Click the copy button and paste it into the site's password field. Store it in your password manager. Hit Regenerate to create a different password for the next account.

Frequently Asked Questions

How do I remember a random password?

You don't — that's what password managers are for. Use a password manager (1Password, Bitwarden, etc.) to store all your random passwords. You only need to remember one master password — and you can use our Passphrase mode to create a memorable one.

Is 16 characters enough?

For a random password using all character sets (uppercase, lowercase, numbers, symbols), 16 characters is extremely strong — it would take centuries to crack with current technology. Our strength meter confirms this for you.

What if a site has weird password requirements?

Some sites limit length or disallow certain symbols. Adjust the settings: reduce length if capped, toggle character sets to match requirements. The strength meter updates in real-time so you can see the impact.

Should I use Passphrase or Random mode?

Use Random for passwords stored in a password manager (maximum security). Use Passphrase for passwords you need to type manually — like your password manager's master password, or WiFi passwords. Four random words are very secure and much easier to type.

Strong passwords don't have to be hard to create. Let cryptographic randomness do the work — then store the result in your password manager. Every account gets a unique, unguessable password, and you never have to remember any of them.
