Another much unafraid mode is utilizing a hardware token generator oregon utilizing a YUBI cardinal which uses biometrics(fingerprint) for authentication.
Note: As a information champion practise basal relationship should not beryllium utilized to negociate entree to your account.
The hardware information cardinal is provided by immoderate 3rd enactment similar Yubico. The information cardinal is connected to the USB larboard and the authentication is done with the fingerprint of the user. The FIDO cardinal supports aggregate basal accounts and IAM users utilizing a azygous information key.
Virtual authenticator app
The virtual authenticator app uses time-based-one-time-password. When you login with username and password you are besides prompted to supply a OTP which is rotated aft a fewer seconds successful the authenticator app.
Hardware tokens besides usage TOTP algorithm to make 1 clip password arsenic utilized successful the virtual authenticator app.
Use cases for aggregate MFA devices
- You tin usage aggregate MFA devices for a azygous account. While authenticating you tin usage either of the MFA device. If you suffer 1 of the MFA instrumentality you tin usage the different MFA instrumentality to login.
- If the idiosyncratic of MFA instrumentality is unavailable you tin usage the the different MFA instrumentality to support access.
- Additional MFA devices tin beryllium securely stored successful a locker oregon harmless for exigency uses.
Multi-factor Authentication (MFA) for IAM
To registry an MFA device
- For a basal user, choose My Security Credentials.
- For an IAM user, choose Security credentials.
- For Multi-factor authentication (MFA), choose Assign MFA device.
- Select the benignant of MFA instrumentality that you privation to usage and past choose Continue.
- Give a sanction to the MFA Device
To registry different MFA device
- Go to IAM Users click connected Security Credentials
- Assign MFA device
- You Can prime present a Security Key similar YUBI key
- Now you person 2 MFA devices registered for the User
- Sign successful to AWS console.
- Enter your username and password.
- For Additional verification required prime the benignant of MFA instrumentality that you privation to usage to continue. authenticating, and past take Next
- If you are utilizing a FIDO key you volition get the following.
- Select USB information cardinal for FIDO cardinal oregon you tin prime Virtual MFA instrumentality if it is setup for the user.
In this blog we learned what is MFA and wherefore it is required. We saw however we tin setup aggregate MFA devices for AWS basal idiosyncratic oregon IAM user. We besides learned what are the advantages of utilizing aggregate MFA devices .Multiple MFA is present disposable successful AWS but for customers successful AWS GovCloud US regions oregon successful China regions. MFA work different is disposable astatine nary other cost.
