How to Use 1Password as an Authenticator

‍

This tutorial shows how to use 1Password as your authenticator app so you can store and autofill two-factor authentication (2FA) codes without switching to a separate app like Google Authenticator or Authy.

Notes:

• The website or service you're setting up must support authenticator app-based 2FA. 1Password will generate and autofill the one-time code each time you sign in.
• If the QR code scan doesn't work, click "Can't scan the QR code?" on the site to reveal a secret key. In 1Password, open the login item, click edit, then "Add More," choose "One-Time Password," and paste the key manually.
  

1. Sign in to the account where you want to set up 2FA - for example, your Google or Slack account and go to its security settings.
2. Look for the two-factor authentication or two-step verification option and select the authenticator app method. The site will display a QR code.
3. Click the 1Password extension in your browser toolbar. It should automatically detect the login item for that site and display it. 
4. Click the ellipsis (three dots) on the login item, then select "Scan QR Code." 1Password scans the QR code on the page and links the account.
5. Back on the website, enter the six-digit code now showing in 1Password to confirm the setup, then save your changes on the site.
6. Confirm the settings to see that 2FA is now active with 1Password as your authenticator.
7. Sign out and sign back in to test it. When prompted for your 2FA code, 1Password will autofill it automatically along with your username and password.
