Available MFA methods for IAM
You can manage your MFA devices in the IAM console. The following options are the MFA methods that IAM supports.
FIDO security keys
FIDO-certified hardware security keys are provided by third-party providers such as Yubico. The FIDO Alliance maintains a list of all FIDO-certified products that are compatible with FIDO specifications. FIDO authentication standards are based on public key cryptography, which enables strong, phishing-resistant authentication that is more secure than passwords. FIDO security keys support multiple root accounts and IAM users using a single security key. For more information about enabling FIDO security keys, see Enabling a FIDO security key
Virtual authenticator apps
Virtual authenticator apps implement the time-based one-time password (TOTP) algorithm and support multiple tokens on a single device. Virtual authenticators are supported for IAM users in the AWS GovCloud (US) Regions and in other AWS Regions. For more information about enabling virtual authenticators, see Enabling a virtual multi-factor authentication (MFA) device.
You can install apps for your smartphone from the app store that is specific to your type of smartphone. Some app providers also have web and desktop applications available. See the following table for examples.
TOTP hardware tokens
Hardware tokens also support the TOTP algorithm and are provided by Thales, a third-party provider. These tokens are for use exclusively with AWS accounts. For more information, see Enabling a hardware MFA device.
