Answer : You have installed MySQLWorkbench as a Snap package. You want to store the database password(s) in the Gnome Passwords & Keys facility. However, a Snap package is sandboxed ; it is not by default allowed to access this service. When you choose "Store in keychain" MySQLWorkbench is blocked by AppArmor. You need to enter a command to allow this package to access the service. The command is: sudo snap connect mysql-workbench-community:password-manager-service :password-manager-service I got this from the discussion at this site. Go to app store . Search for mysql-workbench . Click on permission . Enable Read, add, change, or remove saved password̀s
