Multi-factor authentication (MFA) adds an extra layer of protection on top of your username and password. After MFA authentication is enabled, you need to enter verification codes after your username and password are authenticated. MFA, together with your username and password, ensures the security of your account and resources.
MFA devices can be based on hardware or software. However, IAM supports only virtual MFA devices.
A virtual MFA device is an application that generates 6-digit codes in compliance with the Time-Based One-Time Password Algorithm (TOTP). MFA applications can run on mobile devices (including smartphones) and are easy to use.
You have installed an MFA application (for example, Google Authenticator) on your mobile phone.

Your account is then added to the application. Open the MFA application on your mobile phone, and enter the secret key. To ensure that you can perform MFA-based verification successfully, confirm that you have enabled the automatic time setup option on your mobile phone.
