yahoo mail failed to authenticate

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!

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.

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! :(

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....

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.

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.

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 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.

I am able to access MacMail using Ventura 13.2 on my laptop, but I have a MacBook Air (I mistakenly said MacBook Pro above). Seems crazy that would be the difference though. It's older than I remember, too, at 2020. Time flies! I am going to be very careful about changing my pacbell password going forward. What a PITA.

Another person posted the same instructions a month ago. It depends on the provider... some won't allow it stating, "Generating an app password is currently unavailable." The only way to access email in that case is via web browser.

I lost all my Rogers emails because of Apple support on my Mac. iPhone and iPad had no problem with the new Yahoo password. I think we need to use another mail inbox instead of Apple mail because Rogers have not fixed the problem. And entry level csr are totally useless. Thanks for your response.
