# Open Instance

# Introduction

Once your instance has been successfully created and configured, you can open, or visit it, to begin using the Mautic software.

Each Mautic instance integrates seamlessly with CampaignPRO using SAML SSO technology, allowing you to instantly login into any instance right from the control panel, no username / password required.

# Open instance

To open, or visit your Mautic instance, click on Instances in the navigation menu on the left and then click on the rocket-icon button next to the target instance.

This will open a new tab where you'll be automatically logged into the selected instance as a master user.

# Troubleshooting

Here's a list of common issues you might encounter and their solutions.

In some cases when you're already logged in or your session has expired, you might get that error when opening the instance.

Simply click the rocket button again, and you'll be correctly logged in.
