I want to setup MFA to other IAM users in AWS? Is there a way to do that? I only found that I could force them to authenticate themselves but is there a way for an administrator to setup MFA for other IAM users?
This can be done from the console, but you must be aware that you will need a device to bind it to that the user if they are to be able to login.
To do it you will need to go to the IAM console:
Go to the IAM console
Click the Users menu item.
Click on a User name link
Click the Security credentials tab
Next to the Assigned MFA device label click Manage
You can now sort out the MFA for the user
The administrator would need access to perform this action in IAM.
Just in case you are not aware you can also use the policy on the AWS: Allows MFA-Authenticated IAM Users to Manage Their Own MFA Device on the My Security Credentials Page page to prevent a user from doing anything whilst they do not have an MFA attached.
I dont think so this is possible.
You can enable it for a user but the user needs to go through the steps to establish the MFA.
It defeats the purpose of MFA if a third person has access to it, therefore industry best practice is for a user him/herself to set it up.

At the place where I work, I have to sign-in via SSO to access the AWS dashboard.
How do I see which roles/permissions my user account has?
Every-time I fail to access a resource or perform an action, I am having to ask my team mate if he can perform that action. If he is able to do it, then I infer that my account is lacking a permission.
I am trying to create a docker on AWS. I have created a an account and now I am stuck on this page:
It asks for account ID and IAM username. I do not know my ID. Where is it?
On AWS docs it says log into your account and go to support center, but the support center login requires this same screen. Please let me know if I am doing something wrong.
Click the Sign-in using root account credentials link on the sign-in page and you will be prompted for an email address and password.
This will login as the Root account, which is all-powerful. In fact, it is so powerful that the recommendation is that you should immediately create a new IAM User, assign it Admin permissions and then never use the Root login again. You can assign Admin permissions by attaching the policy called AdministratorAccess.
While you are in the IAM console, you can create an account alias that you can use when logging in via the screen you have shown. It will also give you a URL you can use to access the correct sign-in page in future.
I have been managing an AWS account for about a year. Typical "best practices" security setup:
1 Root Account
Multiple non-Root accounts, including the one I use on a daily basis
All accounts using MFA (I personally use the Google Authenticator app)
I would like to now transfer "ownership" of this entire AWS account (Root account & all) to someone else. While I can certainly give them the username + password to login as Root, they will need MFA setup as well.
The only way I can think of handling this is to:
Disable MFA on the Root account
Give them the logins for the Root account
Trust that they will re-enable MFA as soon as possible
Does the AWS web console provide any better solutions? I'm not even sure if its possible to disable MFA on an account (let alone Root) once its set...
Thanks in advance!
To deactivate the MFA device for your AWS account root user (console)
Use your AWS account root user credentials to sign in to the AWS Management Console.
Important
To manage MFA devices for the AWS account, you must sign in to AWS with your AWS account root user credentials. You cannot manage MFA devices for the root user with other credentials.
On the navigation bar, choose your account name, and then choose My Security Credentials. If a prompt appears, choose Continue to Security Credentials.

Expand the Multi-Factor Authentication (MFA) section.
In the row for the MFA device that you want to deactivate, choose Deactivate.
The MFA device is deactivated for the AWS account
You asked three questions.Let us look on by one
1.Disable MFA on the Root account
To deactivate the MFA device for your AWS account root user (console) follow these steps
Sigin to your AWS Account with Root Creds
On the right corner of navigation pane you can see the My Security Credentials
Select Multi-Factor Authentication
Then mark it as Deactivate against your MFA Device
2.Give them the logins for the Root account
For this you follow this AWS documentation which clearly shows How do I transfer my account to another person or business?.For this there is no need of Technical support package, your Basic Support package is enough.
3.Trust that they will re-enable MFA as soon as possible
For this you have to ask them whoever you are transferring the account to enable the MFA. You can also teach them the need of MFA and it's security needs.
As mentioned, it's possible to remove an MFA from an account once it's been added. You also have two options for transferring the root account with MFA enabled:
If the account is worth the investment, buy and use a hardware MFA. Then transferring the account involves physically transferring the MFA device.
If you want to keep using a virtual device, remove the MFA from the root account and re-add it. While scanning the QR code with your own Authenticator app, take a screenshot of the QR code and store it securely (ideally, print it on paper and immediately destroy any digital copies), or press "Show secret key for manual configuration" and write down on paper the long seed string. The QR code or seed string can be scanned or entered to seed the same OTP number-stream onto the new owner's Authenticator app. Obviously, be aware that if stolen the same data can be used to seed the same stream by anyone, including an attacker, so keep it secure.
I'm looking into the following. I have several AWS users in my account. Some users have console access and programmatic access. All users have a policy attached that enforces the use of MFA. For users that want to access AWS programmatically, this is a problem. For normal access, I know they can just add the token in the CLI. But the problem I have is when we run an automatic process from one of those accounts. You can't just add the MFA token in your code because the token changes, but the forced MFA policy prevents access to AWS which causes an error.
The only working solution I have now is using seperate users for concole access and programmatic access and only enforcing MFA on the console access user. But this is a silly solution and requires people to manage seperate user accounts.
Does anybody have a better solution? I tried to change the force MFA policy so it would only require MFA to work with console access or so it would require a connected MFA device, not an MFA login. But that didn't work.
Sorry if anything is unclear, English is obviously not my first language, please do ask if you need more details.
Thanks in advance!
Is it possible to grant logina#foo.com full access to all services in loginb#foo.com for AWS Web Services? I have a couple different folks working on my team and I wanted to make it easy for them to do what they need to do in our sandbox.
Thanks!
If you are using something#foo.com to log into your AWS account, you need to stop doing that right now, and set up an IAM (Identity and Access Management) account instead.
There is a best practices document here - you want to look at the section under "Manage AWS Accounts, IAM Users, Groups, and Roles" - but in a nutshell:
Use 2 factor authentication on the root account
create IAM accounts for daily use. If you grant admin access to an IAM account, it should probably be set up with 2 factor authentication as well
turn on CloudTrail. Yes, it will cost you a few cents a month. But if you ever need it, you'll really, really wish you had it.
Never, ever, ever check access keys and secrets into a public repository. (The cost for violating this one will be around $5k/hour.)
set up a billing alarm. Estimate what you'll be spending a month, and set up alarms at 25%, 50%, 75% and 100%. That way if something does go wrong (or you accidentally spin up an r3.8xlarge) you'll get a notice quickly.
Every account only has a single 'root', but using "Identity and Access Management" you can create and account users and grant console login and adminstrative privileges inside the AWS console.
Look under the services tab for one named "IAM".
Select 'Users' from and press the blue 'create new users' button
Add a user login name
Once the user's created
Select the user and set a password via "manage password"--without this they can't log in
Press the 'Permissions" tab for the users and select Attach policy
Give the user the 'Administrtor Access' policy.
The user should then be able to log into the AWS console with admin privs and use the API if they want
