yahoo mail failed to authenticate

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.

If you ever experience any issue related to “login failed” in the app.

Try to login to your mail account on a desktop web browser first.. once you’re successfully logged in there then you will not face any login issue with the app on any device.

Apologies for my late reply and thank you for confirming. I'm happy for you that you're able to utilize your MacMail on your laptop. I was just speaking with a manager from our internet carrier yesterday because I had been locked out of my Yahoo mail for some reason and he said that this MacMail issue has been going on for months and is based on Apple's concern with interface security. They continue to meet with Apple regularly, but its ongoing and doesn't look like it will be rectified anytime soon, unfortunately.

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.

Thank you for your comment. I'm glad that you've found my postings somewhat informative and I'm sorry to hear that you're having the same issue. I found this thread on Apple Community after I lost access to my MacMail in early Sept when we needed to create a new email address with Rogers. If I had have known that by letting the Rogers agent temporarily change my Yahoo password in order to create a new email address, I wouldn't have given them permission to do so. Strike one against Rogers.... no one at the entry level of customer service seems to be aware of this issue, its only until you escalate up the chain and open a ticket that you find out what the problem really is. I've spent way too much time on this issue, but I was really annoyed and wanted some answers. Two of our email addresses can't access MacMail, but one still can because the password is neither new or been changed since May 2023. It seems as though I've gone as far as I can go at this point and I will definitely keep you updated if you will do the same.

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.

trying to setup yahoo mail account in the mail app on my apple laptop

after entering username and password i get "yahoo mail failed to authenticate" error

the app was working fine with this yahoo account until connection problems made me delete the account and reinstall it.

Solved. In Mac Mail - Go to Add Account and Select "Other". When prompted for email / password - enter your yahoo email address. For password - go to Yahoo Security Page (https://login.yahoo.com/myaccount/security/) and Generate App Key. (Generate and manage app passwords) Use this 16 character code as password.

Unfortunately it didn't work for me.

I have tried the create app password a few times, and get the same thing failed to authenticate. I am using yahoo web mail for now, which works but is not as convenient as Apple mail.

Not that simple. For many of the people on here, trying to add an account doesn't work. I tried that weeks ago while on the phone with an Apple tech for over an hour. Also can't generate a new app password. This is a bigger issue. Glad your MacMail works for you.

Sorry, I'm just seeing this now.... That's really a shame that you lost all of your Rogers emails on your Mac. iPhone and iPad will still work the same because they do not use the same integration as MacMail, but I'm not 16 anymore and don't want to type long emails with various attachments on my phone. ;-) If you have the patience, call Rogers and ask them to open a ticket for you about this issue and that way you can: 1. Use that ticket to get through Customer Service faster the next time you need to speak with someone and it will be a manager who knows more, and 2. They'll provide you with updates when and if this issue is ever resolved.

I had the same issue on a Mac. I would put in the password and would get a warning that the Yahoo account failed to authenticate. I solved this issue by updating the operating system to the latest version which was Sonoma.

@Tekkaman. You indeed are the MAN! you fixed my problem! I have been tryin for &*&* months to "fix" this. You did it in less than 5 for the non-compie to easily do it. Rock on THANK YOU! Send me an address and Ill mail you a case of brew!

Thanks again

I can unequivocally say this does *not* work on a MacBook Pro Mid 2015 running macOS Monterrey 12.7.5. This is after about 10+ tries doing exactly what is described as working. It does not work on this computer running this version of macOS.

That said, it *does* work on my MacPro 2019 running macOS Sonoma 14.5 which leads me to asking - has anyone found a way to make it work on Monterey?
