Password Generator & Autofill

Free extension for Chrome

A password generator that keeps nothing

Password Generator & Autofill makes strong random passwords inside Chrome, on your computer, from the browser's cryptographic random source. It doesn't save them and sends nothing anywhere. Copy one from the toolbar, or right-click a sign-up field to fill it.

Works in Chrome and other Chromium browsers on desktop, even offline.

The Password Generator & Autofill popup: four random 20-character passwords with digits and symbols coloured, a length slider and four character-set switches

At a glance

What it does
Generates random passwords of 8 to 64 characters in the toolbar popup, and fills new-password fields from the right-click menu.
Where passwords are made
On your computer, inside Chrome, with crypto.getRandomValues. No server is involved.
Data
Passwords are never saved or sent. Only your settings (length, character sets, look-alikes) are stored, in Chrome sync.
Permissions
One install warning: “Modify data you copy and paste”, for copying the password. It reaches a page only when you click its menu item.
Price
Free. No account, no paid version.
Works in
Chrome and other Chromium browsers on desktop, offline too. Not Firefox, Safari or mobile browsers.
Limits
Not a password manager: it doesn't save passwords. Fields inside another site's login frame can't be filled; the password is still copied.

Set your rules once, then copy or fill

  1. 1

    Add it to Chrome

    One click on the Chrome Web Store. The only warning Chrome shows is about copying to the clipboard.

  2. 2

    Set your rules

    Pick a length from 8 to 64, the character sets, and whether to avoid look-alikes. The settings are remembered.

  3. 3

    Copy or fill

    Click a password in the popup to copy it, or right-click the new-password field and choose “Generate and fill password”.

Fits the site's rules

20

A new key for every account

Sign up with a fresh 20-character password instead of reusing an old one, then save it in your password manager.

12

Strict site rules

A site wants exactly 12 characters and no symbols? Set the length, switch symbols off, and every result fits.

0O

Codes you read aloud

Avoid look-alikes drops I, l, 1, O, 0 and o: for Wi-Fi codes, TV logins and passwords written on paper.

What it does

  • Any length

    Drag the slider. The list updates as you drag, and the length is remembered.

  • Four passwords at a time

    Click any one to copy it. “Regenerate” gives you four new ones.

  • The characters you choose

    A–Z, a–z, 0–9 and the symbols !@#$%^&*_-+=. Every set you keep appears at least once, so “one digit and one symbol” rules pass.

  • Avoid look-alikes

    One checkbox removes I, l, 1, O, 0 and o. Digits and symbols are coloured in the popup, so the rest reads in chunks.

  • Right-click to fill

    Fills the field you clicked and its repeat-password partner in the same form, copies the password and tells you it worked.

  • Your current password stays

    On change-password forms, a field marked as the current password is never touched.

Where the password comes from, and where it goes

Each password is made inside Chrome on your computer by crypto.getRandomValues, the browser's cryptographically secure random number generator. Every character is drawn so that each allowed character is equally likely; nothing comes from your name, the site or the clock. No server is involved, so it works offline too.

After that the password exists in two places only: the field you filled and your clipboard, until you copy something else. The extension keeps no list of passwords, no history and no log, and it contains no code that sends anything over the network. It stores your settings, nothing more. It is a generator, not a password manager: save new passwords in Google Password Manager or the manager you use.

What it can and can't do

  • Made on your device

    crypto.getRandomValues in Chrome. No server, works offline.

  • Nothing stored, nothing sent

    No password list, no history, no analytics, no account.

  • One install warning

    “Modify data you copy and paste” is for copying the password. The extension can't read your clipboard or your saved passwords, and it reaches a page only when you click its menu item there.

Questions

Is it safe to use a password generator extension?

It depends on where the password is made and where it goes. This one makes passwords on your computer with Chrome's cryptographic random generator, saves none of them and sends nothing over the network. Chrome shows one install warning, about copying to the clipboard.

Does it store or send my passwords?

No. A generated password exists only in the field you filled and in your clipboard. The extension keeps no list or history; it stores only your settings, in Chrome sync.

How random are the passwords?

Each character comes from crypto.getRandomValues, Chrome's cryptographically secure random source, with every allowed character equally likely. A 20-character password drawn from all 74 characters carries about 124 bits of randomness.

How long should a strong password be?

Use 16 characters or more where the site allows; the default here is 20. If a site caps the length, use the longest it accepts and keep all character sets on.

Why does Chrome warn “Modify data you copy and paste”?

That is the clipboardWrite permission, used to copy the password for you. The extension can put text into the clipboard but has no permission to read it.

Chrome already suggests strong passwords. Why use this?

Chrome's suggestion appears on sign-up forms it recognizes and follows its own rules. This one works in the popup at any time and on any field you right-click, with the length and characters you set: handy for strict site rules, Wi-Fi codes and test accounts.

Will it overwrite my current password on a change-password form?

No. It fills the field you right-clicked and its empty or new-password partners in the same form, never a field marked as the current password.

Is it a password manager?

No. It creates passwords but doesn't save or sync them. After you sign up, save the new password in Google Password Manager or the manager you use.

A strong password, ready.
