I don’t understand the scenario here. Typically, you only need the TOTP (time-based one-time password) from your 2FA app, enter it on your computer, and you can use the computer to access your resources. The app itself is actually not even supposed to be on the same device, as an added layer of security.

It sounds like you need 2FA to run your company’s VPN (is that correct?). On your computer, you would launch the VPN, it’ll ask you for the TOTP (which you get from Aegis on your phone), and then you’re logged in and able to access company resources (on your computer).

Otpclient can open Aegis exports directly.

At a glance, it looks like Aegis generates standard TOTP tokens, which means there’s a lot of software that can do the same thing, so you don’t need to emulate Aegis. I use pass-otp (an extension to pass), but that’s command-line-only, and a lot to deal with if you’re not already using pass. From a quick search, it looks like Keysmith and OTPClient are decent graphical alternatives. From another quick search, OTPClient is available in Ubuntu 23.10.

Edit: Re-reading your post, your issue is that you don’t like logging in on your phone, right? But Aegis just provides the code, you should be able to use the code from your phone to log in on your computer. TOTP codes are only affected by the secret values and the current time, so the code generated on your phone can be used on any device.

my method for running Android apps on my distro is to run an Android 9.0-r2 VM on QEMU/KVM via virt-manager

maybe this might work for you?

here’s a guide I found for setting up Virt-manager on Ubuntu

and here’s a vid for setting up Android x86 on Virt-manager

• not sure if this is the exact same vid I used but it should suffice

hope this works/fits your use case!

There’s nothing special, it can be replaced with any TOTP/HOTP implementation. In particular, oathtool is supplied in most distros (it has only command line interface, probably there are also some GUI tools in your repos). However it does not support JSON key format that is provided as QR code for mobile 2FA apps. You have to copy and paste values from it manually.

However this will likely violate your employer’s security policy. The point of 2FA is that secret key is stored on a separate device, so that it cannot be stealed together with your password.

I recommend to try other Android apps on your phone. I use FreeOTP+ and have no problems with font readability. Some of my collegues use AndOTP and like it.

Firefox has 2FA extensions. Just remember that if both your authentications are on one device, you’re not getting a huge security boost.

Copy the totp seed from aegis and use something like keepassxc to generate the codes

There are surely native totp apps for this on Linux and I haven’t used Ubuntu in a million years but if you really want to do specifically this maybe waydroid.

https://github.com/marcopaganini/termotp is a CLI authenticator program with fuzzy find capabilities explicitly designed to work with Aegis export files.

Just use an app like Authenticator importing the Aegis export file.

you can just use any other OTP application on Linux like https://gitlab.gnome.org/World/Authenticator or https://apps.kde.org/keysmith/, they all follow the same protocol
you can export your keys in Aegis and import them in most applications
