Issue: Logging in with SSH doc shows a QR code

[coccolesto]

Is there an existing issue for this?

Describe the issue

I set up authd for ssh authentication using entraid broker with ubuntu 24.04 LTS.
According to https://documentation.ubuntu.com/authd/stable-docs/howto/login-ssh/# whenlogging by ssh I should receive a qrcode but I receive the test menu only and I have to login manually to https://login.microsoft.com/device.

Maybe I have to install some pkgs not listed in the docs?

Steps to reproduce

Double check your logs

It's on purpose that we don't show the QR code during SSH login because many SSH clients don't support rendering it and there is no way for us to detect at the server-side whether the SSH client supports it or not (see #497 and #545).

thank you,
I use the ubuntu 24.04 ssh client and should work..or not?

[adombeck]

the SSH client on 24.04 would support it, but like I said, there is no way to detect that server-side, so we don't show the QR code at all when SSH is used

[coccolesto]

ok,
so there's no way to use an authenticator (i.e Microsoft Authenticator), only login manually? If so better to update the doc

[adombeck]

the QR code has nothing to do with Microsoft Authenticator. it just encodes the URL https://login.microsoft.com/device. so you have to enter that URL manually but beside that there's no difference

[adombeck]

we should still update https://documentation.ubuntu.com/authd/stable-docs/howto/login-ssh/ since it shows a QR code. I'll repurpose this issue for that.
