Zimbra 2FA: How to enable and set-up 2-Factor Authentication for your HIS-Hosted Zimbra email account
2-step or 2-Factor Authentication is an extra layer of security for your email account. With it enabled, to log into your Zimbra account, you need your password (One thing you know) and a code generated by your smartphone (One thing in your possession).
See the 2FA Authenticators Zimbra supports .
To setup 2-Factor authentication in your Zimbra email account:
- Login to your webmail account: https://zmail.his.com/)
- Once logged in go to Preferences > Accounts.
- Scroll down to Primary Account > Account Security.
- Click on the link: Setup two-step authentication.
- Click on "Begin Setup".
- Provide your email account password, then click Next: It will display a Key: Keep that open and write it down.
The next steps happen on the new device:
- If needed: Install an authentication application on your SmartPhone.
- Launch the Application on your SmartPhone. We will use Google Authenticator as example:
- Click + to add a new account
- Enter your email address
- Click on Enter Key and enter the Zimbra key displayed at step #6, then click Next.
- Enter the code displayed by the Application for this account, then click Next.
- If you entered the code correctly you should see a message saying Success!
You are all set: The authentication app will now generate the codes for your email account.
Access to HIS Zimbra hosted email from applications such as Thunderbird, Mac Mail, Outlook, iPhone Mail, Android Mail, etc. will use the same configuration except you will not use your regular email account password anymore.
Instead, each of your applications or devices will use its own "application passcode" generated in Zimbra. You will need to update the configuration of each of your applications and devices; however, most will simply note that the old password is not working and prompt you for the new one.
