# Profile - Master Data

In the “Master data” section, you can customise your name, email address and avatar. Your email address also serves as the username for your personal user account, and the avatar allows you to add a personal touch to your profile to increase its recognition value. You will also see the ID of your personal user account in the master data section. This can be particularly helpful when requesting support.

| 💡 You can find out how to change your email address [here](https://docs.groupalarm.com/en/article/change-email-address-13otnk5/).
