Authentication
Access to Matrix is based on a standard login function needing User name and password to access your instance. When signing in you also have the option to enter a comment which will be used during the whole session until you either change it or log out. It will be stored with any change to the project's data you make.

You can also login without a session comment, e.g. if you want to read only or if you want to provide a specific comment for every change. If you want to use a comment over multiple sessions, you can tick "remember comment".
The session will expire automatically after 30 minutes (default) without activity. The session timeout can be changed by any administrator here: Password Settings
If you remove the comment you will be prompted to enter a comment whenever you want so save a change.
Additionally we also offer Single Sign-On & 2FA as a paid add-on feature. If you’d like to know more about this, feel free to reach out to your Customer Success Manager or our Support team.
