  1. Add Twofold to Chrome

    Install it from the Chrome Web Store and pin it to your toolbar. Optionally set a master password to lock your vault.

  2. Scan a website’s QR code

    Turn on two-step verification in a site’s security settings, open Twofold and press Scan. The account is added instantly.

  3. Sign in with one click

    Next time the site asks for a code, it’s already at the top of Twofold, or filled in for you. That’s it.

Can a fake site fool it?

Questions

Frequently asked questions

Is Twofold really free?

Yes. No ads, no premium plan, no trial and no account to create. It’s free for good.

Do I need my phone?

No. Twofold creates your codes right in Chrome, using the same open standard as phone authenticator apps. If you want your codes on a phone too, Twofold can show QR codes to transfer them.

Can Google or anyone else read my codes?

No. Your vault is encrypted on your device. If you turn on sync, it is end-to-end encrypted with your master password before it leaves your computer, so only scrambled data is stored. Twofold has no servers of its own.

How does it know which code I need?

Each account remembers the website it belongs to. When you open Twofold, the account for the site in your current tab is at the top, and smart autofill offers it right next to the code field. Lookalike and phishing sites never match.

Can I move my accounts from another authenticator?

Yes. Most authenticator apps can export accounts as a file or as QR codes. Open Import in Twofold, add the file or scan the export codes, and everything comes across in one go.

Does it work offline?

Yes. Codes are calculated on your device from the current time. Only sync needs an internet connection.
