Duo is a multi-factor authentication (MFA) service that adds an extra layer of security to your online accounts. When you have Duo enabled, you will be prompted to enter a code from your phone in addition to your password when you sign in to your account. This helps to protect your account from unauthorized access, even if your password is compromised.
To set up Duo, follow these steps:
- Go to the Duo website.
- Click on Sign Up.
- Enter your email address and click on Create Account.
- You will receive an email from Duo with a link to verify your account. Click on the link in the email.
- You will be prompted to create a password for your Duo account.
- You will also be asked to choose how you want to receive verification codes. You can choose to receive codes via SMS or an authenticator app.
- Once you have created your Duo account and chosen your verification method, you can start enabling Duo for your online accounts.
To enable Duo for an account, you will need to visit the account’s settings page. Once you are on the settings page, look for the “Duo” or “Multi-factor authentication” section. In this section, you will find instructions on how to enable Duo for the account.
Once you have enabled Duo for an account, you will be prompted to enter a verification code from your phone each time you sign in to the account from a new device or browser. This will help to protect your account from unauthorized access.
Here are some additional tips for using Duo:
- Keep your phone secure. If your phone is lost or stolen, you can disable Duo for your account by visiting the Duo website.
- Make sure you have a backup of your authenticator app. If you lose your phone, you will not be able to access your accounts without a backup.
- Consider using a hardware security key. A hardware security key is a physical device that you can use to authenticate yourself when you sign in to your accounts. This provides an additional layer of security beyond Duo.
