Microsoft Single Sign On
Description from store

Use this extension to sign in to supported websites with Microsoft work or school accounts on Windows (10 and later versions) or macOS (11 and later versions). If you have a Microsoft Entra ID on your Windows or macOS computer, this extension enables improved Single Sign On for supported websites. You may still see additional authentication prompts like multi-factor verification depending on the access requirements for various applications, resources, and organizations.

This extension is required for certain device-based conditional access policies for Microsoft Entra ID. https://learn.microsoft.com/en-us/entra/identity/conditional-access/concept-conditional-access-conditions#supported-browsers

For macOS, this extension requires the device to be managed and requires the additional installation of Company Portal: https://learn.microsoft.com/en-us/mem/intune/user-help/enroll-your-device-in-intune-macos-cp

Note: If you are experiencing difficulties with signing in or accessing resources, it could be related to your organization’s device policies. Please submit a support ticket directly to Microsoft through your tenant’s subscription. The developer email address for the extension is not an avenue for customer support.

Just reiterating another reviewer, it is telling me to install it when I have it installed, and now I can't get out of the loop or access email. Microsoft is just nosediving

Adan Warren
This never worked for me and it actually infected my Google search results to make them worse. Do not install this buggy extension.
Ananduprasad Ks
Even after extentions is added , still i get the screen like saying install the extentions
Michael Huang
It automatically removes itself every time when I restart my computer...
Kenny Chung
To say that this extension is bad is an understatement. It needs to be pressed everytime before it works, but it never tells you that that is what you need to do. Classic example of enshitifying a process.
Robin Arcus
Installed the extension, and it will still say it needs to be installed
Snakestry
90% sure this extension never works because Microsoft is disincentivized to make it work. The whole point of it is so I can use Chrome instead of Microsoft Edge at work which Microsoft would obviously prefer I DON'T do. Jokes on them though because nothing makes me want to use a product less than this type of manipulative BS.
Matteo Bianchi

Solution/alternative to the buggy extension: https://learn.microsoft.com/en-us/entra/identity/conditional-access/concept-conditional-access-conditions#chrome-support Summarised: use regedit and go to "HKEY_LOCAL_MACHINE\Software\Policies\Google\Chrome" (create the keys if they don't exist). Then create a DWORD value of 1 with the name CloudAPAuthEnabled. Then reload the policies in Chrome (go to chrome://policy/ and click "Reload policies"), or restart Chrome.

Chris Scull
no help at all
Ishleen Singh
The multi-factor authentication doesn't work properly--often requires approval at least twice in the authenticator app

We need this extension to allow IT admins to use Chrome to access MS admin portals with admin accounts, not with our non-admin work account. This is due to conditional access policies. This thing is not designed great for logging in with a different account than the one you are signed in to Windows with. Every time the sign-in token for the admin account expires in Entra ID, if I close the browser, next time I go to an admin portal, it automatically logs me in with my non-admin user account that I am signed into Windows with, without prompt to choose the account I want to log in the portal with. Often when I hit "sign in with a different account" or "switch account" or "sign out", the log in option proposed only include the work account signed in to Windows and I have to refresh or press back or fill in manually my admin account when it should already be listed as an option. This is not an issue with our conditional access policies, neither is it an issue with our Tennant or our user accounts. It's an issue with the extension's design. When logging in to multiple admin portals on a daily basis, this is a very frustrating waste of time. We don't have these issues with Firefox, but for personal preferences and practical reasons, I prefer Chrome. That said, if this extension doesn't improve soon, I will seriously consider using Firefox for all admin tasks.
Brian Hodge
Install and worked for about a week. Now it thinks it's not installed, but also is... sigh, Microsoft.
Jason Roberts
What a waste of time.

Akshay Deep
Really bad
Sheyan Sandaruwan
when i login a time it needs to remove and add again all time. worst working
Ronny Ager-Wick
This is the worst SSO extension in history. It doesn't work half of the time, and when it does, you usually have to log in multiple times. I bet most of the users were forced to install this by some inept IT manager who decided it was a great idea to waste people's time on fighting defective login procedures by doing it "the Microsoft way". Well done for thinking inside the box, like every other IT manager whose job can be replaced by a one-liner AI prompt. Killing your company's productivity by making sure everyone's work is dependent a company who couldn't care less about you, I guess that's just a bonus!
Rajnish Kumar
Worst, not working.
Chris Cloer

Jarosław Kamiński

Derek Nash
Frequently gets stuck in a loop where I can't get to my applications, culminating in a message that I don't have this plugin, even though I do.
Nasi Nduna
It does not work.... the error is still there no adjustments i make and no amount of googlig leads to a resolution, The Single sign on is basically not doing its job at all.
Toby White
This extension used to work really well, before Edge wasn't so dominant. Something seems to have broken along the way though as it doesn't seem to work so well anymore.
