 Although Azure Front Door supports TLS 1.2, which introduced client/mutual authentication in RFC 5246, currently, Azure Front Door doesn't support client/mutual authentication (mTLS) yet.
 
-You can configure the minimum TLS version in Azure Front Door in the custom domain HTTPS settings using the Azure portal or the [Azure REST API](/rest/api/frontdoorservice/frontdoor/frontdoors/createorupdate#minimumtlsversion). Currently, you can choose between 1.0 and 1.2. As such, specifying TLS 1.2 as the minimum version controls the minimum acceptable TLS version Azure Front Door will accept from a client. When Azure Front Door initiates TLS traffic to the origin, it will attempt to negotiate the best TLS version that the origin can reliably and consistently accept. For minimum TLS version 1.2 the negotiation will attempt to establish TLS 1.3 and then TLS 1.2, while for minimum TLS version 1.0 all four versions will be attempted.
