Identity verification is a complex task since the inception of modern society. The amount of privacy woes related to unique identifier as well as eventual identity thefts are rising day by day; mainly because of the inherent entanglements in the societal structure.

The discovery of the internet and online ‘virtual’ identities added more spice in this topic. Well, my mother’s maiden name could be a viable way of verifying my identity, but there are some side effects as well.

At the beginning of communication over internet, setting up a nickname should be enough create a (virtual) identity. With time, new services started to appear which combined email, messaging, calling, shopping and a lot more domains under one umbrella. Nicks were not enough to handle the bubble.

While email addresses combined with additional levels of verification (popularly known as Multi-factor authentication aka MFA) are proven to be viable alternatives of typical online identity validation, end users are facing troubles to handle multiple accounts.

OpenID: a decentralized authentication protocol

To mitigate the issue, developers came up with open and decentralized authentication protocols such as OpenID and OAuth. With the help of these methods, one can use several online services using a single online identity. For example, you can connect with Google services using your Apple devices.

However, macOS users recently faced a major roadblock while trying to access their Gmail accounts using the built-in Apple Mail app. The authentication seemed to be broken, resulted in an infinite verification loop.


PiunikaWeb highlighted the topic in this article, where we also mentioned the fix of this bug pushed by Apple in the updated Mail app via latest beta of macOS.

Interestingly, a huge chunk of Mac users are getting this weird message about macOS accessing their Google account data via their Gmail account since the same period of time. Looking fishy (or phishing), isn’t it?


As a matter of fact, this prompt is universal for every Mojave (to be specific, 10.14.4 and above) user. People affected by the authentication bug also got the same notification.

Just updated to Mojave 10.14.4. The only previous connection between any Google accounts I have and my Apple world is sharing my Google calendar with my Apple calendar (I can see on all my devices).

Now I’m getting a request in Mac OS calendar to enter the password for the Google account. “Google requires completing authentication”. The pop-up opens safari and takes me to a page that says macOS wants the ability to do all of these (no pick-and-choose possible):

– Read, compose, send, and permanently delete all your email from Gmail (not necessary – I don’t use Apple mail on the Mac for access to my Gmail)

– See, edit, download, and permanently delete your contacts (um, no. In any case, my contacts are already in iCloud)

– See, edit, share, and permanently delete all the calendars you can access using Google Calendar (this is what I’m looking for, although I really just want to “see”. The rest is unnecessary)

– View and send chat messages (not needed)

As you can see, the extra level of authentication is not just about emails. Elements like the contacts synced with Google or your calendar entries now require you to specifically grant access to be accessed from a third party app/service (in this case, macOS).

Yes, I believe it is legitimate. It was connected with Google Notes. (I disabled google notes and then re-instated and it asked to connect with Macos.)

When I blocked Macos, I no longer had access to Google Notes on my iMac.


bkennelly, a Platinum Product Expert of Gmail community, confirmed that the prompt was an after effect of full fledged OAuth2 authentication support in macOS.

It looks legitimate. I am going to ask around, but it looks like MacOS is finally supporting OAuth2 authentication, as iOS has for some time.


Apple community members seconded the claim as well.


Digging a little deeper, we can reassert the same thing. Google recently changed the 2-Step verification process for G Suite, which should directly affect the users.


Different screens on different browsers: You may see different flows on Chrome, Safari, Firefox, Edge, and other browsers. Previously the service provider (Google) was responsible for showing these dialogs. Now the web browser is responsible. As a result, the flow may be different on each browser.

Delivering the authentication dialogue via browser indeed streamlines the verification process, but the obscure documentation can make it scary for end users – as we have seen in the aforementioned threads.

Rest assured, your Google account data should be fine.
