Configuring two-factor authentication on an Exchange account

Objective

If you wish to increase the security on your Exchange account, you can enable two-factor authentication (2FA). This will generate a random code that must be entered when you log in, in addition to your password. This code is generated using a one-time password (OTP) app, which must be installed on your smartphone or tablet.

This guide explains how to enable two-factor authentication on your Exchange account.

Requirements

• an OVHcloud Exchange solution already set up
• an OTP mobile application installed on your Android or iOS smartphone or tablet

OVHcloud Control Panel Access

• Direct link: Exchange
• Navigation path: Web Cloud > Exchange > Select your platform

Instructions

For the initial configuration, you need to enable two-factor authentication on the Exchange service before enabling it on an account.

Switch to the Security tab. 1. Under “Two-factor authentication”, click on Enabled. 1. To finish, scroll to the bottom of the page and click on Save changes.

Step 2: Enable two-factor authentication on an account

After enabling two-factor authentication on the Exchange service, you can then enable it on each one of your accounts.

Go to the Email accounts tab and click on ... to the right of the account on which you wish to enable two-factor authentication, then click on Enable two-factor authentication.

To link the Exchange account to your OTP app, log in to your webmail.

At the first attempt to log in, a QR code will appear. Use your OTP app to scan it, then enter the code that the app generates to log in.
