Each lab comes with a unique password. We set an environment variable called `LABPASSPHRASE` with the following command. The variable is later used to generate local user passwords and connect to our switches to push configs.

``` bash
export LABPASSPHRASE=`cat /home/coder/.config/code-server/config.yaml| grep "password:" | awk '{print $2}'`
export LABPASSPHRASE=`awk '/password:/{print $2}' /home/coder/.config/code-server/config.yaml`
```

You can view the password is set. This is the same password displayed when you click the link to access your lab.
