During deployment I believe Bamboo creates a local admin account which the deplorer can use to configure additional settings though the web interface after the initial deployment.
The Username for this credential is "admin" is there a default password e.g.( admin, password, passphrase, atlassian, bamboo, etc.) kind of like a consumer router?
when we installed Bamboo lately we were asked for a username and password (according to Bamboo setup guide). There is no admin-default password (which would be a huge security flaw).
In case you forgot the admin password you would have to reset it.
