Considering this as feature request, marking it as untriaged for further triage from dev team. 

There are website blocking extensions in chrome store which are rendered useless because guest browsing is now allowed without an option to disable it. Using supervisor control on the chrome account leads to another problem - supervised account does not have the option to install extensions. Please bring back this very useful option which lets a user disable guest browsing. Otherwise I would have to switch to another browser.

Adding some more precise label to raise awareness of this issue.


It seems this option was removed when we transitioned to MD settings but unless there was some good reason for that I think it was an omission and should be considered a regression.

I think some people might need to use this option. Some install useful extensions in their browser yet wanted their children or other people to not use the computer with uncheckable history.
This is particularly important with shared computers, as such, this feature to disable guest browsing is very useful and important.

 Issue 804629  has been merged into this issue.

I can see the merged issue as of last week, and appreciate the note that it was classified as a regression, but I just wanted to make sure this issue didn't die by the wayside.
Also, I can confirm that this issue exists on Linux as well.

the importance of this issue cannot be overstated!
all the time taken in setting up extensions to block inappropriate websites is rendered useless with this!
I uninstalled all browsers (even edge), but not being able to disable guest browsing makes it all moot! Hoping this is feature is added back as soon as possible ....thanks!

@dpapad, is this being tracked anywhere? See the old checkbox that used to exist in chrome://settings on Desktop here: http://ccm.net/faq/40997-how-to-lock-access-to-google-chrome-disable-guest-browsing

We should try to merge this as far back as possible.

@tubckley:
I believe this was intentional. See previous discussion on this below.

It was a conscious decision to remove these checkboxes. We discussed with the UI team, the supervised user team, and the Unichrome team. Everyone was on board.

The checkboxes were quite confusing and caused a number of issues with the new profile management UI we launched in MD settings/user manager. Also, they were never a "security" mechanism, because it was trivial for any user to simply open settings and toggle the checkbox back on in order to re-enable Guest mode.

The modification we put in place was that if all non-supervised/child profiles on a given machine are locked, then we automatically disable guest mode. We believe this achieved the same functionality that people were looking for without any of the UI complexity. I would mark this as WontFix, unless you'd like to revisit this issue with the Chrome UI team.

Per #13, I am closing this.

I am sorry but you have not at all addressed the issues raised here by users before closing it. And it's really frustrating after waiting for this to be resolved for so many months. 

First of all, there doesn't seem to exist any option to create supervisor/parent and supervised/child profiles in Chrome anymore. Please let me know if I am wrong. 

Secondly, even when there did exist the option to create such profiles, it didn't solve the issues that I and others had previously mentioned - which is - if we used the supervisor/parent profile, the website blocking extensions in chrome were rendered useless because guest browsing was allowed in supervisor mode (guest browsing doesn't allow installation of any extensions); if we used the supervised/child profile, then also we couldn't use any website blocking extensions (supervised/child profile didn't allow installation of any extensions either). 

Regarding your assertion in Comment 13 that it was trivial for any user to simply open settings and toggle the checkbox back on in order to re-enable Guest mode, I would say that it was not as "trivial" as you would think for users who used website blocking extensions - because we would simply add the specific URL where we changed this setting, to blocked websites (in the website blocking extension). 

Basically, website blocking extensions, which MANY users find very useful for various purposes (from procrastination self-control to child/employee access) are rendered totally useless if guest mode cannot be disabled. And no, chrome's own supervisor/child profiles were not even close to the flexible options that such extensions provide. 

Until chrome develops that supervisor/child functionality at such a sophisticated level, please bring the option to disable guest mode.

I have a suspicion.
A new joint venture between Chrome and PornHub including a reduction of tools to stop porn.
The goal is the people's brainwash, starting from children in this bastard world!

 Issue 847996  has been merged into this issue.

Please re-open this issue, as the reason it was closed is no longer valid.
#16 was right in that supervised users were removed, and with them, the option to lock your profile.
Without that, guest mode does not get disabled.
The reason they were removed is because FamilyLink is supposed to take their place.
However, FamilyLink is an app for phones.

This problem is not resolved.  Please reopen issue.  I currently see no way to block guest mode on chrome.  If there is, please explain.  If not, please restore this useful function for same reasons as 4, 10, 16.  Obviously, your users want this control back.
