yahoo mail failed to authenticate

If you don't change your OS or buy a new Mac - you are fine. But I bought my Mom a Mac Mini to replace her super slow iMac and now she can't have Mac Mail (well - with Rogers)? She's in her 80s and been with Rogers forever and mail is super important to her, but learning a new app is going to be painful. Might be time to have her look at Bell or Teksavvy and get her mail from.... er..... anywhere else.

I have read through this thread and tried many things. Finally, something worked, so I wanted to share. First, I am on MacOS Ventura 13.4.1. I started having this issue when up upgraded my OS. After trying what people have suggested in this thread, the following worked:

1) I have generated 3rd party app password on Yahoo as suggested in the thread below

2) I have removed saved Yahoo password from my Safari browser and (just in case) from the Keychain app

3) In adding an internet account, I didn't click on "Yahoo" instead I clicked on "Add another account" and just entered my yahoo user name with "@yahoo.com" domain.

4) I have etered the 3rd party app password that Yahoo has generated for me.

My Yahoo! Mail works!

Hope this works for you too!

Yahoo has gone to this too...

Yahoo App password…

Generate and manage third-party app passwords

Some older, third-party email apps (that do not use our Yahoo branded sign in page) require you to enter a single password for login credentials. To access your Yahoo Mail account on these apps, you'll need to generate and use an app password. An app password is a long, randomly generated code that gives a non-Yahoo app permission to access your Yahoo account. You’ll only need to provide this code once to sign in to your third-party email app.

Same for me, "Sorry, this feature is not available at this time!"

I have tried to login after setting up 2 step authentication and logging in using the mail app up to the point of entering the verification code either emailed or texted to me to get an Authentication failed message again!

I feel if i hadn't deleted yahoo from Apple Mail I might have been OK? As this is a month later, did any of you eventually get in?

Running Mac OS CATALINA 10.15.7

Get all the same responses and issues in all 4 pages of REPLIES.

I have used YAHOO generate 3rd Party PSWRD APP and get PSWRD NOT RECOGNIZED.

Also get the Yahoo Login Failed, Try Again Later.

I've attempted to create a new 'INTERNET MAIL' Account. When I use my Yahoo ID for the ACCOUNT, I receive Err Msg: ACCOUNT Already Exists.

For my Technical Purpose, I won't upgrade to newer MAC OS(If that's only solution, I'll just buy a new MAC MINI🙄). Any One who can assist me if fixing this, would be really appreciate. I'm very luck in that when I originally configured APPLE EMAIL, that I retained ALL MAIL/MAILBOXES on YAHOO SERVER, when YAHOO MAIL was transferred to APPLE MAIL.

Yahoo has gone to this too...

Most likely biggest factor is using Other in Mail setup, then using a Browser that doesn’t have Yahoo PW stored init to get the App PW.



"After clicking the - symbol did you click remove from all or turn off account?" NO‼️ I just want APPLE MAIL to AUTHENTICATE w YAHOO, NOT do anything that appears as drastic '-' DELETE YAHOO MAIL BOX/APPLE MAIL and REMOVE/CLOSE YAHOO ACCOUNT PREFERENCE ENTRY in the APPLE INTERNET ACCOUNT SYSTEMS PREFERENCE PANEL. I don't want to loose 11 YRS of E📩MAIL 😱. I still appear to have YAHOO E📩MAIL, prior to 28 JUL in APPLE MAIL.

So before '-', I'd like to know that I'm not going to trash my currently installed APPLE MAIL APP.

Can You clarify exactly what will happen if I DELETE '-' the YAHOO ACCOUNT PREFERENCE ENTRY in the APPLE INTERNET ACCOUNT SYSTEMS PREFERENCE PANEL⁉️

Thanks

Respectfully

That's what happened. So to summarize the solution to the Problem,

In the APPLE INTERNET ACCOUNTS PREFERENCE PANEL, I deleted '-' the original YAHOO ACCOUNT as displayed. I then utilized the '+' to add a new YAHOO ACCOUNT. I used the YAHOO 3rd PARTY PASSWORD as the PSWRD during the initialization process.

I did not get a 'FAILED to AUTHENICATE' Msg. And then APPLE MAIL proceeded to download all of YAHOO MAIL BOX.

Please Note that when You DELETE '-' the YAHOO ACCOUNT in the APPLE INTERNET ACCOUNTS PREFERENCE PANEL. It will delete the APPLE INTERNET ACCOUNT 'YAHOO'. So, I'd recommend having a MAIL BACKUP in case there was a problem recreating the YAHOO/APPLE MAIL ACCOUNT when restablishing APPLE MAIL. In my particular case, YAHOO downloaded 35K/11 YRS of E📩MAIL. It took around 4 hrs on my MAC MINI running CATALINA.

Hope this information is useful to someone.

But YAHOO/APPLE MAIL was again functional.

Unfortunately I have the same problem both to Catalina and iPad (ios12). It started when I had to change the mail password and now I cannot access to my account via Mail app. I tried to generate app password from yahoo (from multiple machines, browsers and mac/Pc), but the same alert is showing (Sorry, this feature is not available right now!).

All I get is sent to ATT site that has zero info on third party passwords. Any aka yahoo site redirects me to ATT site! On the yahoo mail site on the browser, there is no "security" menu link to click!

What is the mail app's name? the requierments are:

Sign in to your Yahoo Account Security page.

Click Generate app password or Generate and manage app passwords.

Enter your app's name in the text field.

Click Generate password.

Follow the instructions below the app password.

Click Done.

I do not know what my app's name to enter it in the text field...

Rogers is useless. I spent more time on the phone with them this past week than I care to remember with 3 separate techs only to have a higher up tech 'expert' blame Apple for being too busy launching their new products to solve this issue. I also spent over an hour with an Apple tech who just laughed at Rogers' claim. I've tried to generate a new password to set up a new account like others have successfully done on this forum, but Rogers won't allow me to do so. I keep getting the message, "Generating an app password is currently unavailable." I wonder where the problem stems from...??? Please let me know if you've been able to sign on to your MacMail... Thanks.

You're not alone...

But it is Apple, tying the Mail App to the OS, it can't be modernized except to Upgrade the whole OS!

Just wondering, have you tried a different browser?

Are you using any VPN or anti-virus software?

Rogers told me that it won't be fixed for at least another month. I wonder how long they've been telling customers that. The Apple tech I spoke with told me that Verizon bought Yahoo and since Rogers and Bell banded together to keep Verizon out of Canada, this must be retribution. No competition up here.

Yes, I've tried a different browser, same result. No VPN or anti-virus software.

Thank you for your feedback, I appreciate your reply. I'll try the OS upgrade later, although so far I've been unable to do so.

Best of luck my friend... I recently had to borrow an MBA during a month in the hospital, came running Mojave, could not for the life of me setup Mail for any of my accounts, including Yahoo, Upgraded to Catalina, still impossible circles! :(
