Click<\/p>\n\n\n\n
Add MFA<\/pre>\n\n\n\nAWS validates the codes and enables MFA.<\/p>\n\n\n\n
Step 8: Verify MFA Status<\/h3>\n\n\n\n
You should now see<\/p>\n\n\n\n
Assigned<\/pre>\n\n\n\nunder the MFA section.<\/p>\n\n\n\n
Your IAM user is now protected with Multi-Factor Authentication.<\/p>\n\n\n\n
Logging in After MFA Is Enabled<\/h3>\n\n\n\n
On future logins:<\/p>\n\n\n\n
\n- Enter your username.<\/li>\n\n\n\n
- Enter your password.<\/li>\n\n\n\n
- Enter the 6-digit code from your authenticator app.<\/li>\n<\/ol>\n\n\n\n
Only after successful verification will AWS grant access.<\/p>\n\n\n\n
AWS CLI Login with MFA<\/h3>\n\n\n\n
If your IAM user uses the AWS CLI, obtain a temporary session token.<\/p>\n\n\n\n
Example:<\/p>\n\n\n\n
aws sts get-session-token \\\n --serial-number arn:aws:iam::123456789012:mfa\/username \\\n --token-code 123456<\/pre>\n\n\n\nExample output:<\/p>\n\n\n\n
{\n \"Credentials\": {\n \"AccessKeyId\": \"ASIA********\",\n \"SecretAccessKey\": \"****************\",\n \"SessionToken\": \"IQoJb3JpZ2luX2VjE...\",\n \"Expiration\": \"2026-07-01T18:00:00Z\"\n }\n}<\/pre>\n\n\n\nExport the temporary credentials:<\/p>\n\n\n\n
export AWS_ACCESS_KEY_ID=ASIAxxxxxxxx\nexport AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxx\nexport AWS_SESSION_TOKEN=IQoJb3JpZ2luX2VjE...<\/pre>\n\n\n\nVerify access:<\/p>\n\n\n\n
aws sts get-caller-identity<\/pre>\n\n\n\nAWS CLI Configuration<\/h3>\n\n\n\n
Configure your IAM user:<\/p>\n\n\n\n
aws configure<\/pre>\n\n\n\nExample:<\/p>\n\n\n\n
AWS Access Key ID:\nAWS Secret Access Key:\nDefault region:\nDefault output format:<\/pre>\n\n\n\nConclusion<\/h2>\n\n\n\n
Enabling Multi-Factor Authentication (MFA) is one of the simplest and most effective ways to secure your AWS environment. By requiring a second verification factor in addition to a password, MFA significantly reduces the risk of unauthorized access due to compromised credentials. Whether you access AWS through the Management Console or the AWS CLI, enabling MFA should be considered a mandatory security best practice for all users with access to your AWS resources.<\/p>\n","protected":false},"excerpt":{"rendered":"
