2fa | Two-factor authentication on the command line | Authentication library

I worked on setting up 2FA while doing ssh in EC2 instance. But after the setup instance is still not asking for 2FA code and directly logs my user i.e. ubuntu into the server.

I did following steps to setup 2FA:

1. Install Google Authenticator PAM module.

   sudo apt install libpam-google-authenticator

2. Add auth required pam_google_authenticator.so to /etc/pam.d/sshd

3. Restart ssh sudo systemctl restart sshd.service

4. Update sshd_config with following:

   ChallengeResponseAuthentication yes PasswordAuthentication no

5. Run command google-authenticator

Please help me resolve this issue. Thanks in advance.

I have a application build with .NET Core. This application is very simple, but the problem is that I have to integrate a 2FA app (PingId) for double security instead of one simple Login. I am guided to use SAML, for building bridges between Service Provider and Identity Provider. I have found some solutions online, and one of them that is open source is itfoxtec.identity.saml2.

What I want to know is that, is there anyone who can clear the way how this works? I mean I cannot understand some url in appsetting.json file.

Here is a demo of this file:

https://github.com/ITfoxtec/ITfoxtec.Identity.Saml2/blob/master/test/TestWebAppCore/appsettings.json

For example IdPMetadata key is a xml file that has to be provided by Identity Provider administrator?

SigningCertificateFile is a generated certificate by my Service Provider app or is something builded inside the application, if that is how to generate it?

I have the following scenario. Currently a Wordpress site was hosted on an EC2 server. There is no deployment strategy in place. It was using the AWS CLI to deploy the data from local to the server.

Problem For various reasons, I don't want to take it over that way of deployment and am currently considering putting the deployment process into a GitHub Action. Which in itself wouldn't be a problem if it weren't for the 2FA check.

Using the AWS CLI, I am forced to enter the code displayed in my MS Authenticator app into the CLI to proceed.

Question: Is it possible to deploy via GitHub Action and 2FA? I guess almost no? But what do I know?

I know it invokes different Lambda instances for different routes (like connect, disconnect, default, etc) on the Websocket API. But what happens for different messages on the same route, does it keep the Lambda instance running for new messages until disconnect?

Let's say, I am building a login form with 2FA. I take username, password and process it, and then I want the 2FA code from client. Can I do this with a single Lambda instance?

In the Near, transactions signed by a 2FA-protected wallet are done in a special way (contract confirmation) and are not like regular transactions. Signer and receiver id the same wallet. Sample transaction: https://explorer.near.org/transactions/9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY

How to work with them properly, where to find them in Indexer? How do I get the data correctly, what contract and method the user signs?

I haven't used Google Cloud in years and today I've logged in and I've found that there are several projects in https://console.firebase.google.com/u/0/ and https://console.cloud.google.com/cloud-resource-manager?organizationId=0&authuser=0 that I didn't create.
I'm not the owner of those projects and I can't do anything with them.

What can I do to clean this up?
My GMail account is protected with 2FA, how did they managed to create these projects?

Any hint about where to look for help would be great as Google doesn't seem to care unless I pay for a support plan.

Searching for an answer to this finds a lot about GitHub credentials but nothing on this specific issue. I am starting to work with the PowerShell (PoSH) Cmdlet 'Get-Credential' because my company uses Two-factor Authentication (2FA), so a username/password won't work to remote from my desktop (user account) to a server (Admin account). Additionally, I have just started using VS Code. The issue is that when running a simple PoSH snippet, in PoSH ISE using Get-Credential I get a popup that lets me select the certificate that I need and then enter a Pin. When I run this same snippet in VS Code, the popup never appears. Does anyone understand why this is, and can I resolve it?

Here is the snippet for reference.
