Own Identity service vs. using ready 3rd party services


I’d like to know what benefit gives us using own idnetity service instead something which is ready to use eg. IdentityServer4?


IdentityServer 4 is a very mature solution, however, you need to ask yourself a question - do you really need to have a rather complex OAuth/OIC mechanism available in your solution? Maybe issuing a JWT using built-in system libraries will be good enough method of authentication, thus it really depends on your scenario (as usual) :slight_smile:.
