2. Navigate to the clients.conf file (/etc/raddb/clients.conf).
3. Add the following snippet in the clients.conf file:
   client ProductServerName
   {
   ipaddr = xxx.xx.x.xxx
   secret = <secretCode>
   nastype = other
   }
4. Restart the RADIUS server.

Step 2: Configure M365 Security Plus for RADIUS

1. Select RADIUS Authentication.
2. Enter the IP address or the name of the RADIUS server.
3. Enter the Server Port number for RADIUS authentication.
4. Select the protocol used for RADIUS authentication from the drop-down list.
5. Provide the Secret Key that was added to the clients.conf file in the RADIUS server.
6. Set the Username Pattern.
7. Set a duration for authentication Request Time Out duration.
8. Click Save.

Backup verification codes

Backup verification codes allow users to log in when they don’t have access to their phone or face issues with one of the second-factor authentication methods. When enabled, a total of five codes will be generated. A code, once used, will become obsolete and cannot be used again. Users also have the option to generate new codes.

Enabling the Backup Verification Code option

• To enable backup verification codes, check the Backup Verification Code box.

Registering for backup verification codes

• Users need to click the Manage Backup Verification Codes link to view the codes.

  

• Users can also download the codes as a text file, print them, and get them delivered to their personal email address; they can also generate new codes.
• Users need to click the Manage Backup Verification Codes link to view the codes.

  

Using the backup verification code to log in

• To use backup verification codes during login, users need to click the Don't have verification code? link in the second-factor authentication page.

  

• On the backup verification code page, they need to enter one of their backup verification codes and click Verify Code to log in.

Advanced Settings

You can fine-tune your 2FA implementation for M365 Security Plus with the Advanced Settings menu. This allows you to enable 2FA for help desk technicians with Microsoft 365 authentication, set up trust for browsers, and disable 2FA for a select list of help desk technicians.

To access advanced settings,

1. Log in to M365 Security Plus as a technician who can modify Two-Factor Authentication settings.
2. Navigate to Delegation → Other Settings → Logon Settings.
3. Click the Two-Factor Authentication tab.
4. Toggle the Two-Factor Authentication switch to Enabled.
5. Click Advanced Settings.

Under Advanced Settings, you can configure the following settings:

• 2FA for Microsoft 365 Technicians
• Display Trust this browser option when technicians login using 2FA.
• Exclude 2FA for the selected help desk technicians

2FA for Microsoft 365 Technicians:

To allow SSO by default, 2FA is disabled for technicians who use Microsoft 365 authentication. If this option is enabled, technicians will have to go through the product's 2FA method, even though they are logged in using Microsoft 365 MFA.

Configuration steps:

1. Select Enable 2FA for technicians who use Microsoft 365 authentication.

Display Trust this browser option when technicians login using 2FA.

1. Select Display Trust this browser option when technicians login using 2FA..
2. Enter the number of days for which the browser should be trusted. This option is set to 180 days by default.

Exclude 2FA for the selected help desk technicians:

2FA is a secure method of authentication. However, there are some scenarios where administrators can be allowed to bypass it. For example: in environments with lower risk profiles, help desk technicians can be given more flexibility on how they login to the product or when they login to the product frequently, bypassing 2FA can be convenient for them to conduct their tasks. You can now set up M365 Security Plus to exclude 2FA for a select list of help desk technicians.

Configuration steps:

1. Select Exclude 2FA for the selected technicians.
2. Click on the icon to add technicians for whom 2FA should be excluded.



3. Select the help desk technicians for whom 2FA should be excluded. You can also filter the list of technicians by Authentication Type using the Filter By dropdown.
4. Click OK to exclude 2FA for the selected help desk technicians.
