By default mongodb has no enabled access control, so there is no default user or password.
//Terminal
//Connection mongo
mongo --port 27017
//Switch to admin
use admin
//Create new User
db.createUser({ user: "mongoadmin" , pwd: "mongoadmin", roles: ["userAdminAnyDatabase", "dbAdminAnyDatabase", "readWriteAnyDatabase"]})
//If you using docker
//First running
//default username: mongoadmin
//default password: mongoadmin
