## Accessing via Terminal on Linux or Mac

To connect to the GSDC UI server using a terminal on Linux or Mac after setting up OTP, you need to undergo two authentication steps. 

The first authentication is carried out using the regular password, and the second authentication requires the verification of the issued OTP token.

First Authentication:

<pre data-overflow="wrap"><code><strong>First Factor: [Enter your regular password here]
</strong></code></pre>

Second Authentication :

```
Second Factor: [Enter the OTP code here]
```

\<ex>

```sh
$> ssh -p [port number] test_ipa@[target UI's hostname]
(test_ipa@[UI]) First Factor: [Enter regular password]
(test_ipa@[UI]) Second Factor: [Enter OTP code]
Last login: [last login details]
[test_ipa@[UI] ~]$
```
