Secure Hosted Email with 2FA and app passwords Print

Two-factor authentication protects webmail sign-in with a time-based code from an authenticator app. Mail applications cannot normally enter that extra code, so they should use separate app passwords.

Enable two-factor authentication

1. Open your Hosted Email service in the ArkHost Client Area.
2. Open the App Keys tab.
3. Select Set up 2FA.
4. Sign in with the mailbox address and its current password.
5. Open the mailbox profile settings and enable two-factor authentication.
6. Scan the QR code with your authenticator app and save the recovery information.

Create an app password

1. Return to the App Keys tab in the ArkHost Client Area.
2. Select Add App Password.
3. Select the mailbox and enter a recognizable name, such as Work laptop.
4. Create and confirm a unique password.
5. Allow only the services that device needs, such as email, mobile sync, or Calendar and Contacts.
6. Select Add App Password.
7. Enter that password in the mail application instead of the main mailbox password.

Revoke access

Select the bin button beside an app password. The associated application loses access immediately without changing the main mailbox password or affecting other devices.
