As a AWS Free-Tier user you are entitled for lot of free compute power.
This is AWS way of saying "Please experiment and learn".
But expirements go wrong sometimes. In this case they can go really bad if you are not carefull.
Here are the 4 things you need to do first after signingup for AWS Free-Tier subscription.
#1. Set billing alert.
#2. Enable MFA
#3. Delete root account access keys
#4. Bring IAM dashboard's "Security Status" to all Green 5/5
Ok, i will take you through each change and explain you why.
