The short answer
- Use the browser's built-in generator if it appears on signup forms and you are comfortable saving the result in that browser's password manager.
- Use your trusted password manager's extension when you want generation, encrypted storage, and autofill across browsers and devices.
- Install a generator-only extension only when it provides a workflow you genuinely need and its permissions, privacy practices, source, maintenance, and update path withstand review.
- Use a website or installable app when you need local generation without granting a component ongoing access to browser pages.
Built-in generator, manager extension, or generator extension?
| Option | Best for | Main tradeoff |
|---|---|---|
| Browser built-in generator | Creating and saving ordinary website logins | Low setup, but tied to the browser's storage and sync ecosystem. |
| Password-manager extension | Generation, storage, and autofill across sites | Powerful page access may be necessary; the vault provider becomes a high-trust dependency. |
| Generator-only extension | One-click output or unusual policies from the toolbar | Adds code and permissions to the browser without necessarily solving secure storage. |
| Standalone generator website | One-off generation with no installation | Requires manual transfer and secure storage of the result. |
| Installable web app | Offline generation without a traditional extension | Does not automatically fill websites or store credentials. |
Permissions to review before installing
Permission warnings describe what an extension can do, not whether the developer will misuse that access. Compare every requested capability with the extension's stated purpose.
- Read and change data on websites: required for automatic field detection or filling, but broad all-site access can expose page content. Prefer on-click or specific-site access when the workflow still works.
- Clipboard read or write: writing supports one-click copy. Reading is more sensitive because the clipboard may contain credentials or other private data.
- Storage: preferences may be reasonable, but determine whether generated passwords or history are retained and whether that storage is encrypted.
- Active tab: grants temporary access to the current tab after a user gesture and is narrower than permanent access to all sites.
- Tabs and browsing activity: can reveal visited URLs and page titles; a simple toolbar generator should explain why it needs this.
- Network communication: check whether the privacy disclosure identifies analytics, remote services, accounts, sync, or generated-value transmission.
How to install a Chrome password generator extension safely
- First try Chrome's built-in suggestion: select a password field or right-click it and choose Suggest password or Generate password.
- If that does not meet the workflow, open the Chrome Web Store directly and examine the exact listing—not an advertisement or similarly named copy.
- Review the publisher, privacy disclosure, update date, support link, permission request, user count, reviews, and whether the source repository matches the published product.
- Select Add to Chrome only if every requested permission is justified. Chrome explicitly advises approving only extensions you trust.
- After installation, open Extensions → Manage extensions → Details. Restrict site access to When you select the extension or specific sites when possible.
- Generate a non-production sample first. Verify the extension's controls and storage/history behavior before trusting it with a real account workflow.
How to find, pin, disable, or remove the extension
- Find it: select Chrome's Extensions button beside the address bar. Pin the extension if you want its icon to remain visible.
- Review it: open
chrome://extensionsor choose Extensions → Manage extensions, then select Details. - Disable it: turn off its switch on the Manage extensions page. This is useful while diagnosing page or autofill conflicts.
- Remove it: right-click a visible extension icon and choose Remove from Chrome, or select Remove on the Manage extensions page and confirm.
When an extension is not the best answer
Do not add a generator-only extension merely to avoid visiting a bookmark. Every extension increases the browser's code and update surface. Chrome or Firefox's built-in generator may already cover ordinary signup fields, and a password-manager extension usually provides more complete value because it stores and autofills the result.
For unusual length or character rules, use the local browser generator. For a standalone experience that reopens from an app launcher and works offline after its first load, use the installable password generator app. This site does not currently publish a Chrome or Firefox extension.
Are open-source password generator extensions safer?
Published source lets reviewers inspect the random-number API, permissions, storage, network calls, and build configuration. That is useful evidence, but it does not prove that the store package matches the repository, that anyone has completed a meaningful review, or that future updates will remain safe.
Check release provenance, dependency health, issue history, maintainer activity, license, and whether the installed package can be reproduced from the source. For this site's generator implementation and tests, see the open-source password generation algorithm.
Frequently asked questions
Does Chrome have a password generator extension built in?
Chrome has a built-in strong-password suggestion connected to Google Password Manager; it is browser functionality, not a separately installed extension. Third-party extensions are optional.
What is the best password generator extension?
For most people, it is the extension supplied by the password manager they already trust, because it can generate, save, and autofill. Evaluate the entire manager's security, recovery, audit, update, and privacy model rather than choosing by the generator popup alone.
Can a browser extension read my passwords?
An extension's ability depends on its permissions and implementation. An extension allowed to read and change data on a page can interact with page content, including form fields. Review and limit site access, and remove extensions you no longer need.
Why did Chrome disable an extension?
Chrome may disable an extension that is unsupported, unsafe, corrupted, or requests newly added permissions. Review Chrome's warning and the extension details instead of automatically re-enabling it.
Can I use this site as a Chrome extension?
No. Generate My Password offers a website and an installable PWA, not a Chrome extension. The app can launch separately and work offline after first load, but it does not read or fill fields on other websites.
