I’m new to sonarqube and I installed it on my machine but when I run it I get this error
jvm 1 | 2021.07.12 19:28:37 WARN app[startup] Default Administrator credentials are still being used. Make sure to change the password or deactivate the account.
what you see in the logs is just a warning to hint you that you are currently using default credentials (admin/admin) which need to be changed after the first login. Is anything not working that makes you think this is an error?
can you describe what you did and where (specially when) you see this warning? it should be gone after you changed the admin password and restarted sonarqube
