Chrome & Edge · v1.0
Authenticator generates the time-based 2FA codes you use to sign in — right next to your address bar, no phone required. Compatible with any service that supports Google Authenticator.
A rotating one-time code, the way it appears in the popup. This one's just for show.
Since this is a direct download (not the Web Store), you load it once through developer mode. Takes about 30 seconds.
Extract the downloaded extension.zip into a folder you'll keep — deleting it later removes the extension.
Go to chrome://extensions (or edge://extensions) in your browser.
Flip the Developer mode toggle in the top-right corner.
Click Load unpacked and select the unzipped folder. Done — pin it to your toolbar and start adding accounts.
