One way or another, you can change all your personal info on Brilliant.
How do I change my name?
You can change your name yourself once per year from your personal info settings page. We include the once a year limitation to ensure that there's a level of accountability within the Brilliant community, as profile names are publicly visible, but we also understand that you may need to change your name again within a given year. If this is the case, you can always write to us at email@example.com, and we'll be happy to update your profile.
As a policy, all name change requests are handled by a single member of our support team, and any prior name(s) you may have had will not be mentioned. Unfortunately, however, your profile URL cannot be changed, and may include elements of your original account name. If this is difficult in any way, our support staff will be happy to help you switch to a new account, though you will not be able to retain the course progress you've made.
How do I change my birth date?
You can change your date of birth once during the lifetime of your account from your personal info settings page. If you need to change your date of birth again, please reach out to our support team at firstname.lastname@example.org.
How do I change my location, or any other personal info?
You can change the rest of your personal information, including your location, from your personal info settings page. There are no limits to the number of times you can change this information.
