If you want to remove your account on Edmodo, a platform to get students connected, you can easily do that in the Settings of your account.
I’ll show you below how I managed to close my profile permanently using a desktop computer:
1 Go to www.edmodo.com
and log in by entering your email address and password on their site.
2 Select your picture in the upper right corner and Settings in the menu
3 Scroll down to the bottom, where you will see: Deactivate your account
4 Enter your password and remove the account
A message will appear:
Your account will be closed within 48 hours.
