Can't disable Password Manager

[slprogrp]

Is there an existing issue for this?

• I have searched both open/closed issues, no issue already exists.

CefSharp Version

133.4.21

Operating System

Windows 11

Architecture

x64

.Net Version

4.8

Implementation

WinForms

Reproduction Steps

I am using CEFSharp in a .NET 4.8.0 WinForms project. I am unable to disable the CEF Password Manager. I have a page with a login, and I don't want the CEF Password Manager prompt the user to save the password.

I have tried setting:
cefSettings.CefCommandLineArgs.Add("enable-password-manager", "0");

and also:
requestContext.SetPreference("credentials_enable_service", false, out string error);

But neither of these worked.

Is there a workaround for this issue?

Expected behavior

The CEF Password Manager should be disabled and not appear prompting the user to save log-in details when they log-in on a web page.

Actual behavior

The CEF Password Manager is not disabled and does appear prompting the user to save log-in details when they log-in on a web page.

Regression?

I never disabled it in when I first used CEFSharp, but it never showed. Now it shows and I can't disable it.

Known Workarounds

I have not found a workaround, but I do need one.

Does this problem also occur in the CEF Sample Application

No

Other information

If I just run the cefclient.exe using the exe name with no cmd args, the issue does happen:

cefclient.exe

If I run it with the cmd args the issue does not happen:

cefclient.exe --multi-threaded-message-loop --no-sandbox --use-alloy-style

After some more investigation I have found that this issue does not happen when I don't set the RuntimeStyle to Chrome:
CefSharpSettings.RuntimeStyle = CefRuntimeStyle.Chrome;

I had set the RuntimeStyle to Chrome some time ago to fix another issue where an alert wasn't popping up.
I have updated to the latest CEFSharp version 136.1.40, and removed my code that set the RuntimeStyle to Chrome.
This fixed the Password Manager issue, and it appears that the alert not showing issue has also been resolved.
Now to test that nothing else is broken..... :-)

I have tried setting:
cefSettings.CefCommandLineArgs.Add("enable-password-manager", "0");

This is not a valid command line argument.

and also:
requestContext.SetPreference("credentials_enable_service", false, out string error);

A quick search suggests this is likely correctly preference to use. https://magpcss.org/ceforum/viewtopic.php?f=6&t=18608

When you set the preference would be very important though. Calling this after the browser has been created is unlikely to work.

In future please use Discussions to ask support questions. Just because you haven't gotten something working doesn't mean it's a bug. The password manager is entirely implemented in Chromium.
