[Bug]: Duo Authentication Box Does Not Appear

[sr66139p]

Describe the bug
The Duo 2FA box does not appear, preventing me from logging in

To Reproduce
Steps to reproduce the behavior:

1. Go to open the app
2. Try to sign in with an account protected by Duo
3. Go to your domain's login page

Expected behavior
I expect a textbox to appear allowing me to enter my 2FA code. I also expect a checkbox that says "Don't ask again for 6 days"

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: Debian 12 Bookworm (Gnome)
• Installation source: deb
• Version 0.5.1

Additional context
Add any other context about the problem here.
Also, did you tried another build (AppImage, deb, rpm)? I tried an older deb 0.3.0

I also have this problem at my University. I guess it's back to the web version.

I have a similar problem with a company saml login page. The email signin box correctly takes me to the saml page but that page shows "you will be redirected in a few seconds" for ever and I can't use the app anymore.

As a first debugging step for some obvious things I could think of, I checked the user agent used by prospect-mail. If I'm not wrong is is set in the code as "chrome". I installed a user-agent switcher on firefox and used the same string: everything works as expected on the web version.

[zeitounator]

As a workaround to what looks like the same problem (see my latest comment), I have iteratively downgraded from 0.5.1 -> 0.4.0 and problem is gone. Interestingly enough this has also fixed #298

[zeitounator]

Although my first test under firefox above is non conclusive, I strongly suspect the regression has been introduced by b0a7d6e when changing the UserAgent. Let me know if I can do anything to test and help debugging this issue in order to fix it. Thanks.

I had a similar issue.

I can login through my org's SSO page and proceed to duo. The title bar would indicate it moved to the Duo page, but the page itself remained entirely white and unloaded. I never encountered a redirect page - straight from SSO to Duo prompt.

Clicking Reload in the toolbar menu for Prospect Mail would reload the page but would result in a Page access not allowed error (duo error).

I can also verify that the issue isn't present in 0.4.0. It works just fine.

Can you try the latest 0.5.2 version available (.deb, AppImage, rpm, etc):
https://github.com/julian-alarcon/prospect-mail/releases/tag/v0.5.2

If you are using snap, you can also try the current beta channel:
sudo snap refresh prospect-mail --channel=beta

This is still an issue in the latest release, @julian-alarcon

The easiest fix is to set contextIsolation to true (which is the default since Electron 12). I've tested this on a local copy already, and it worked just fine.

[zeitounator]

Although I login on a different saml page, this isn't fixed for me either (tested with 0.5.3). Easy test case: try to login with email [email protected]. You will be directed to the saml entry page where you can wait for ever for a javascript redirection and form never shows up. Rolled back again to 0.4.0.

@julian-alarcon : Let me know if it's ok to still follow this point here or if I should create a separate issue.
@8bitZeta : care to share the changes you made to test contextIsolation? I'd like to test as well if it fixes my a bit different issue. Thanks.

I had the same issue, 0.5.2 and 0.5.3 did not fix my problem. Reverting back to 0.4.0 fixed it for me.

[8bitZeta]

@zeitounator, go to src/controller/mail-window-controller.js and comment out line 93...

That line should be contextIsolation: false... Commenting it should enable contextIsolation...

That's the only change I made to get my Duo to work.

[zeitounator]

Sorry for the long delay. For memory: my problem is not exactly the one described in this ticket but similar (i.e. a SAML login redirect page is not followed and displayed).

After login in successfully a few weeks ago with version 0.4.0, snap upgraded the package again to latest prospect-mail and I was able to run since then on the stored credentials. I had to rotate my password last Friday and the bug strikes me again this morning. So I took the time to test.

I checked out the latest git version on main branch and started (i.e. yarn && yarn start). After entering my mail on Microsoft form I get directed to my company SAML page showing "Please wait" for ever and I'm stuck.

I then applied the fix from @8bitZeta above (i.e. remove line 93 contextIsolation: false in src/controller/mail-window-controller.js ) and start again. This time I'm able to proceed all the way through saml authentication.

Edit: Redirecting this to the more generic #312 issue and the #314 implementation which fixes the issue.

Hi, I have a similar problem using Prospect Mail 0.5.4 and a freshly installed Ubuntu 24.04.1 LTS

[zeroz41]

Same problem on 0.5.4 on arch linux. After org sign in "Duo Security - Two Factor Authentication" page is blank white screen and never loads, making this unusable. Reproduced many times.

[Draxiss314]

Pop!_OS user here; identical issue.

same in fedora 41
