Auth 2.0 Error 400 on Mail account

I try to add my account but I got this message


Authorisation Error
Error 400: invalid_request

What's wrong with Apple and Google? Google asks to contact the developer, yes Apple...


It's so frustrating...

SOLUTION


In google, goto "Manage your Google account"...


On the left menu, select "security"...


Scroll to "2-Step Verification" (Mine was on already)...


Scroll to the very bottom of the "2-Step verification" page and select "App passwords"...


Select app menu, select "Mail" in the "Select Device menu, select "Mac"...


Click the "Generate" button and copy the password in the yellow box...


Open the mail app...


Archive your mail for the account you are fixing (if you need to, most people wont)...


Open system preferences from the Apple Menu...


Select "Internet Accounts"...


Delete the broken Gmail account here by clicking on it and hitting the - at the bottom of the window and close that window...


Go back to the mail app...


In the "Mail" menu, select "preferences" and add a new account with the + at the bottom of the accounts list making sure to select "other mail account" as the account provider and click "continue"...


enter the name for the account, enter the gmail email address, and paste the password you copied from the yellow box as the password.


TADA!

As Google states it is their requirement, and their decision to impose it upon others.


If a product or service becomes too difficult or inconvenient to use don't use it. It seems Google wants to force you into using something else.


I don't understand what's so great about Google anyway. The product they sell is you. The emails you send are theirs. What are you getting out of that deal?

Then put and .. . . and vent to the E-mail Severs of the Users' Choice.


We hear similar complaints directed towards Apple for imposing things on Users in the iOS / macOS they do not like.


Don't like Google, Don't Apple.


Maybe some other platform would be a better fit.


Has the user tried Linux - Oh don't them either 😔

funny thing is with my Raspberry Pi Zero2 which is 15 pounds I can use all and have better performance than on this Mac with newer OS... I remember when internet was useful and usable, now thank you to giant techs here we go. I have also Issues with email from outlook 365... Thunderbird works great for gmail, you need to use an older version but works... it's crazy Google makes trouble for Apple and Apple can't do anything about it

sadly it doesn't work unless you get the two steps authorizations, giving a phone number to google... talking about privacy


Privacy? Phone number...?


The desire to use Google Mail while maintaining any semblance of privacy demonstrates cognitive dissonance. You fixated on a gnat and can't even see the elephant in the room.

All good to me, I just want to use the mail app, without having to setup two steps verification for the dozen emails I use... also I have other emails as Office3654 which do not work anyway on Mail - wouldn't apple be so kind to send a patch to those or is there a real good alternative? Thunderbird is working at the moment but it's graphic makes me wish I use a rapsberry Pi on Day to Day as it's more refined. DO I need to switch to Linux on my laptop just to use email? I am pretty happy with everything else this mac can do, I just want to use an email on it, you know, they thing I have been doing for over 30 years and suddenly is not working anymore due to corporate greed?

Feb 24, 2023 5:01 AM in response to Owl-53

Sure of course, I will use mail in browser, no one wins and possibly I will install linux on my laptop as it works... I remember when people were saying that Apple "It just works" I can't see how they can get this blow from Google and do nothing about it. You can't use MAIL app anymore in 2023. an email program. And it's not only google, it's office too.

I surmise I could be more clear about it: Google has absolutely no incentive to let you use Apple's email client. None. There is nothing in it for them. Google and its parent company Alphabet exist for the sole purpose of harvesting and selling your personal information. If not for that fact Google would disappear. Poof. Gone. Wiped out. Google wants you to use something else.


Apple on the other hand embraces protecting personal information, has zero interest in selling yours, and actively incorporates those principles in their core business model. You don't have to use Apple's products or services either. If you don't agree with them, use something else.

in any case thank you for your effort: these are my conclusion


BEST SOLUTIONS: Install Linux

SECOND BEST SOLUTION: get a windows latpop

THIRD BEST SOLUTION: use your browser

FOURTH BEST SOLUTION: thunderbird

FIFTH BEST SOLUTION: give up and start to use pen and paper.


thank you technology the only winners are those who gave up.

But Apple do insist you buy overpriced new equipment from them at an alarmingly increasing frequency to have that security and privacy, thus ensuring their bottom line. And considering Apple's market cap is about twice what Alphabet's is, that seems to be working for them quite well, but less so for we poor consumers who can no longer afford to fund their greed.
