Is Hotmail safe?

Low risk

Hotmail sends Microsoft OAuth client credentials to Microsoft's token endpoint during sign-in and token refresh.

Hotmail's packaged background auth flow includes a Microsoft OAuth client secret and sends it with authorization-code and refresh-token requests. These token exchanges go to Microsoft's common OAuth v2 token endpoint as part of sign-in and session refresh.
