I know that the RPC username and password for the node are generated upon runtime of the blockchain in the specific node, but is it not possible to provide them as runtime parameters or something?
I haven't seen the user and password as runtime params in the official docs. I also tried specifying
-rpcuser=foo and -rpcpassword=bar but it didn't work. Still random password was generated.
My last try would be to manually replace the content of the multichain.conf file, but if I want to connect a service to the node, that means that I have to start the blockchain (in order to generate the file), then stop it, replace the content with my username and password and then start it again?
