yahoo mail failed to authenticate

My Yahoo account worked just fine on my iMac with Catalina, until today. Now no matter how many times I enter my password it won't log on in Apple mail. It works on the Yahoo page, on my MBA, which runs Ventura, and all my mobile devices. I suspect that Catalina is now considered too old an OS for Yahoo!

I tried generation a password as suggested for 3rd party apps, and that didn't work. If anyone has a solution I would love to hear it. This is annoying to say the least.

Thanks... upgraded to Ventura this evening and still no luck. Mac Mail was working fine until last week when a Rogers administrator asked me to change my Yahoo password in order to add a new email address to my account. Wish I had have known that by changing the password I would only be able to use Yahoo mail instead of my Mac Mail, which is lacking. The other email address on the account is still working fine with Mac Mail access because that Yahoo password was not changed. Grrrrrr....

The Latest from Rogers... use a Browser...

Generating an app password is currently unavailable but don’t worry you can still access your email via Web Browser at mail.rogers.com. Additionally, you can integrate iPhone & Android devices. To see how, Set up a Yahoo! account on a device - Rogers.

When asked for an app in the dialog box of Yahoo password generator in security section I wrote "mail" and then all of the following

as described worked. I have my Yahoo Mail account in the Mail app !

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. "mail"

Click Generate password.

Copy password

Go to Mail app

Add new mail account

Put your ...@yahoo.com

Paste the generated code from yahoo security and you're done

My password is about a year old, so that is not the problem. I suspect it is Yahoo has decided that Catalina is too old, because my Yahoo mail works on my MBA with Ventura. So far I haven't found a solution other than using Yahoo web mail.

Just for the sake of completeness, I tried again today to use my Yahoo mail on Catalina followed all the suggestions, and got the same results, create new password unavailable and failed to authenticate.

No it's happening on the latest Ventura as well. If you were unfortunate enough on Rogers to miss the working App Password, which hasn't worked for months, then there is no other way it will work now. This is all on Rogers and has nothing to do with Apple, and specifically "some user"@rogers.com emails.

I disabled the Avast antivirus and now I can create an app password from Yahoo Account Security page.

But unfortunately even with this new generated password mac mail both from macbook and ipad could not sign in to my Yahoo account. It alerts that the password is wrong. The strange thing is that after any attempt for singing in I see via web browser into Yahoo mailbox that Yahoo sent me emails notifying me that a new device has sing in into my Yahoo mail.

Agreed - its definitely a Rogers problem that they still cannot fix and blame Apple. I received the same old voicemail from Rogers this afternoon stating that there has been a delay solving this issue, but they are still working on it. I get the exact same message every week. The problem has been going on for months.

Interesting. We just had a Bell sales guy going door to door the other day and while he was doing his song and dance to get me to switch, I mentioned the Yahoo and Mac Mail issue to him. He said that the issue wasn't happening with Bell, not that I believed him or expected him to know anything technical because he's in sales. I didn't know anything about the MacMail issue until it affected me, either. Anyway, while I'm sorry to hear that you're having the same issue, it proves that's it not only a Rogers issue so I can't hate on them too much. (at least not in this instance!) Its definitely a Yahoo issue and good luck with that getting fixed anytime soon. I upgraded from Catalina to Ventura as some posters suggested and it didn't make any difference. I've also tried to reset my account, not possible. Your email on your phone is still the same because the phone is not using the same interface as your MacBook. Anyway, frustrating for sure because I much prefer the MacMail, but I have no option other than to wait and get my weekly phone messages from Rogers until it gets fixed. Thanks for reaching out.

Previous attempts said generate password not available. So today I tried again and generated an app password for Mail. The password it generated didn't work said "incorrect password". I would really like if Yahoo fixes this.

Thanks for all the help. I had to change my pacbell/yahoo password yesterday and suddenly I couldn't log into my mac mail on my 2014 iMac running Catalina 10.15.7. I was able to log in on my phone and newish MacBook pro no problem. I followed the instructions here and was able to log in with the one-time password. Mine was actually called something slightly different, but it was under the email section of my pacbell account. I have had this email forever (thus the pacbell.net designation!) but I may need to think about migrating. Also may be time for a new computer!

Hi Monica,

The same thing happened to me when I had to change my yahoo password back in early Sept. I now have a new MacBook running Ventura and am still not able to access MacMail. Don't run out and buy a new computer, its an issue with Yahoo and its been going on for months. I get weekly updates from my carrier that the issue is still being worked on, to no avail.

Thanks for letting me know! Very disconcerting. This is a long time email that will take a lot to change so the fact that it's not working with new products from apple is crazy. I hope your carrier gives you good news soon. My laptop is running Ventura 13.2 and worked without the workaround that I had to do with my older iMac.
