Password Authentication For AWS ec2

Question

good day. I have an EC2 instance of AWS where I host my website. I currently upload files using Filezilla. To connect I use the .pem file. My question is if this is the safest thing or should I create a password for the instance?

Answer 1

Keypairs are much safer for accessing a system. Keypairs are effectively impossible to be guessed and they are not transmitted during login.
