+* Up to version 1.4, only internal MFA was supported. User can use MFA methods configured in his profile.
+* Since version 1.5 (currently in alpha), MFA can be configured per location, and administrators can choose whether a location will use internal MFA or external OIDC/SSO provider.
+
+Depending on location settings, you may use:
+
+* Internal MFA - You must have at least one MFA method configured in your profile. For a detailed tutorial, [check out this article](../setting-up-2fa-mfa.md).
+* External MFA - You will be redirected to an external site, where authentication is handled by your OIDC provider, for example Google/Microsoft.

 ## External MFA
 
 1. Open Defguard client, select your Instance and click **Connect** next to location with required MFA
