# Gns3util cluster control auth set default user

## gns3util cluster-control auth set-default-user

Mark a stored user as the default for a cluster

### Synopsis

Mark one of the saved users as the default for a cluster.
When no --user flag is given on subsequent 'ctl' commands, the default user for
that cluster is used automatically.

Requires --cluster (-c) to identify which cluster to update.
If \[username] is omitted a fuzzy picker opens so you can choose interactively.

```
gns3util cluster-control auth set-default-user [username] [flags]

  gns3util ctl auth set-default-user -c mycluster   # opens picker
