Failed to authenticate with Google

Same here. Kicked out of all of my Google accounts. Same issue exactly.

Same. very frustrating

Same here. The same issue has been reported starting today, June 25, in the Safari form and in Google's Gmail Help form:

Google Password Required, Authentication Failed

Google Groups

It appears that some are attributing the issue to 10.10.3, but I've been running 10.10.3 since it was released and I was able to authorize my Google account using two-factor authentication without a problem. I've not experienced a single issue until today. I also tried adding a different Google account that I own via System Preferences > Internet Accounts that has two-factor authentication turned off . I clicked the Google graphic and entered my login information and received the same "Failed to authenticate with Google" message. However, I received an email from Google that I had used my Google account to sign in to my Mac.

I get the feeling something isn't quite right on Apple's end.

EDIT: So I tethered my MacBook Pro to my mobile phone, provided my credentials in Internet Accounts, and it worked. No "Failed to authenticate with Google" error. I switched back to my home wi-fil, tried logging in again, then I received the error. I live in SoCal, my mobile carrier is Verizon Wireless, and my home ISP is Time Warner. This is very odd but at least I'm not being bugged by that annoying notification.

This just hit both of my Apple devices tonight. Prompted to enter Gmail password by OS/system preferences. Accepts password, displays which apps are getting which data, but fails to update and login properly. Password works with web browser. Fails with the authentication mechanism built into 10.10.3 and 8.3. Two-factor authentication fails. Old (no longer should be required) app specific passwords are not accepted by the first login screen.

Interesting. Not even the Gmail iOS app can log me in. Network unavailable.

Same exact issue. Gmail iOS gives same "Network unavailable" error. Was able to add my gmail account back to Mail using the "other account" option, however eventually it requested the password again and stopped working.

I'm having the exact same problem, was weird though when I used my cellular connection on my phone it authenticated. I have Time Warner Cable, maybe it's some kinda ISP blocking issue. I can login to G-mail fine.

Thanks. I live in So-Cal and have TWC too. Tethered my laptop to my phone and error went away. Definitely a TWC issue.

I Also did that and it began working fine on my iPad. Haven't tried on my MacBook yet. I also have twc and live in San Diego. I read in another thread that it may be a router issue? How likely is that vs it being an issue with twc? Although thinking about it now, why would it all of a sudden be a router issue? Wouldn't surprise me that it has to be on twc's end.

EDIT:

Tethered my phone to my macbook and re-added my google account in internet accounts and it seems to work. Let's see what happens when I reconnect to my home wifi. So far it hasn't asked for my google password...yet...

This is so bizarre.

Same for me. Also in southern California, also on TWC. Seems like quite a coincidence.

I definitely think it's an ISP issue. I use my Google account to login to Feedly and it won't load on wi-fi (TWC) but when I tether to my phone (Verizon Wireless) it works fine.

Replying to my own post earlier: It's been 10 minutes since I got it working again and OS X still hasn't asked for my google account password and Calendars is synching and pushing just fine. Fingers crossed it stays this way!

What I did was this: tethered my iPhone (at&t) to my macbook pro and re-added my google account. It worked. Then I reconnected to my home wifi and so far it's fine.

I chatted with a TWC representative a few moments ago and here's what I was told:

TWC Rep: at 8:47:41

I regret to inform you that there is a maintenance going on from Google server end, engineers

have been made aware of the problem. They are working to resolve it as soon as possible.

TWC Rep: at 8:48:29

I request you to access your services after sometime. It will be resolved soon.

You: at 8:49:29

So just to clarify, the issue is with TWC and it's TWC engineers who are working to fix the issue?

TWC Rep: at 8:50:39

The issue is form the Google server end, We have got an update on that.

TWC Rep: at 8:50:52

Google is working on it.

You: at 8:51:32

Got it. Thanks. Have you been given a time frame in which they hope to resolve the issue?

TWC Rep: at 8:51:56

As of now there is no estimate time, however I can assure you that it will be fixed by end of the

day.

thanks!

I had the same problem on both my iPhone and Mac, after changing my password on my g.xxxx.edu google apps account, used by my university. I could go to system preferences and try to update the password for the account as prompted, and the authentication appeared to succeed, but I got the "Failed to authenticate with Google" message when I tried to accept the management of the account by Google. There was stale data in there somewhere. Both devices failed. I could use the Gmail app and the web interface, so I knew the account itself was ok.

Here is how I finally resolved it.

I went to Settings->mail

I deleted the account from the mail app on my iPhone. Attempting to re-install as a Google email failed (no message on the phone, but I knew why from

the message on the Mac). But it may not have been necessary to delete the account (see below), so try leaving it there.

I installed a new account from the settings->mail page on the phone via "other", putting in my username, thatsme@g.xxxx.edu and the imap server as

imap.gmail.com, with the username thatsme@g.xxxx.edu and the password, and the outgoing mail (smtp) server as stmp.gmail.com, username blank. If needed, the imap port is 993 with SSL and the smtp port is 465 (this is needed, it has to be changed from the default).

This information can be seen by opening your Apple mail app on the Mac, right clicking on a Google account, and clicking on "edit account".

The iPhone was able to verify the data and create the new account.

Then I was able to successfully enter the new password and complete updating the mail application on the Mac. Evidently the manual configuration on the iPhone cleared the stale information at Google and the process could complete.

Unfortunately, the smtp.gmail.com outgoing server rejected my username at g.xxxx.edu. However, I was able to go back to the settings->mail screen and successfully reinstall the thatsme@g.xxxx.edu on the phone as a Google account. I deleted the not-quite functional account that I installed manually.

Now the Apple mail apps are working on both the Mac and the phone.

(repost from thread Failed to authenticate with Google...?)

TLDR: Don't block "partner.googleadservices.com"..

I finally found "my answer" (as it seems to be different for everyone..) I use a custom hosts file to try to cut down on the ad/javascript crap that today's web spews at us all (*) It turned out to be that blocking "partner.googleadservices.com" seems to cause the problem. Why, who knows?

(*) As long as the FDA is going to treat the Internet under Title 2 or whatever as if it were a *railroad* - they should set up a tax to pay for sites to be used and get rid of all the ads. Only problem would be what seems to happen with ALL taxes - they become slush funds for politicians.. So, never mind.
