SOCKS5 authentication support

Reported by, Jul 2 2013 Back to list

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36

Example URL:

Steps to reproduce the problem:
1. Launch chromium from the command line with proxy specifications
2. chromium --proxy-server="socks5://foobar:66" --proxy-auth="user:pass"
3. Pages won't load

What is the expected behavior?
Chromium will successfully connect to the proxy and browse the web through the proxy.

What went wrong?
SOCKS5 authentication support appears to be unimplemented. 

Did this work before? No 

Chrome version: 27.0.1453.110  Channel: stable
OS Version: debian testing
Flash Version: disabled

Correct: socks5 proxy auth is not implemented.

Also note that --proxy-auth= is not a valid flag.

Does this work for you on other browsers? As I recall Firefox doesn't implement it either.
Firefox does not support this, although there has been a patch proposed. The relevant bug is:

Rekonq, Konqueror and KDE in general does not support SOCKS5 authentication. GNOME also doesn't support socks5 autnetication, as shown in 

Arora and many non-browser QT-based apps do support it, as do multiple GTK apps. The lack of secure proxy mechanisms is frustrating.

Maxthon supports SOCKS5 authentication (
Are there any updates on this?
It'd be nice if *one* of the major browsers would finally get around to exposing this.

Yeah this is ridiculous, SOCKS5 is not new or anything, PLEASE ADD THIS NOW.
Chromium, you refuse to implement APNG. Maybe you want people to use WebP/M and that's okay. What's the reason behind this? Are we dumb for wanting to use SOCKSv5? Is there a better alternative coming so it's unnecessary to spend time implementing this? What?

For people who want to use an authenticated SOCKS server with Chrome, a neat trick is to terminate the security using a SOCKS client/server combo on your end.

Going to go ahead and archive this bug.  Sorry guys, this bug is not on anyone's radar, and this is very unlikely to happen, given the fairly low usage of authenticating SOCKS5 proxies.
I think what you mean is that it isn't on any Chromium developer's radar. It's obviously on the radar of the people who have starred it as important to them. I'm disappointed, but will look for other options. Thanks for the honest update.
Indeed, that's exactly what I meant.
Please reopen this!!!

It is almost 2017 and the only browser (that I know of) that supports socks5 authentication is some scammy Chinese browser called Maxthon which has been caught stealing peoples personal info. >>>

Please reopen this issue and finally implement Socks v5 authentication already!

I agree this needs to be implemented, it's ridiculous it's not done already holy shit. 
FF is adding this support [] and author of FoxyProxy will provide a user interface to enter username/password.
Why would you comment in an archived post to mention that a DIFFERENT BROWSER has some feature? This is why I can't ever follow these things.

2017 is going to be the year of the VPN, where VPNs and proxies see unprecedented usage as governments around the world start trying to de-anonymize and regulate the content of the internet, and net neutrality comes ever closer to being eliminated.

Maybe FireFox adding this feature will bring the attention to it that it deserves, since authenticated proxies have exploded in popularity over the last 2 years when this was deemed a non-issue.

I completely agree that this should be implemented, however you should know that password is sent in clear text and I think the data as well, so it's not helping much against governments.
This should definitely be implemented. At this day and age proxies (or VPNs) are a must have. A socks5 proxy server is particularly easy to set up, if only Chrome would support it.
I vote for protected socks proxy server support in chrome.* web extensions API — let us know if we should create a separate ticket for chrome.* API support. user:password@host:port format in PAC-scripts is also desired.
Dear god, I need this functionality so much :( please implement it
2017 is coming to an end, 6 years after the issue was opened, doesn't even seem to be acknowledged. 
It's acknowledged in #9, and deemed not a priority to fix given how rare *authenticating* SOCKS5 proxies are. 
We need SOCKS5 authentication support. When you will add it?????
Firefox already added this
