Discover The Essential: AWS EC2 Default User And Password

instanews 09 Jun 2024

Are you struggling to remember the default user password for AWS EC2 instances?

The default user for Amazon Elastic Compute Cloud (EC2) instances is ec2-user, and the default password is randomly generated upon instance creation. It's crucial to change this default password for security reasons. Leaving the default password unchanged makes your instance vulnerable to unauthorized access.

To ensure the security of your EC2 instances, it's essential to establish strong passwords and adhere to best practices for password management. Regularly updating passwords and employing complex combinations of characters, including uppercase and lowercase letters, numbers, and symbols, can help protect your instances from potential security breaches.

Additionally, consider implementing multi-factor authentication (MFA) for enhanced security. MFA adds an extra layer of protection by requiring a second form of authentication, such as a one-time password sent to your mobile device, when logging into your AWS account or EC2 instances.
