yahoo mail failed to authenticate

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.

@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!

Hi tekkaman65535

I've been trawling the internet to find a solution to my macbook mail app keep saying yahoo mail failed to authenticate and finally came across your solution. However, I'm now wondering whether you will actually see my message as I don't know if you will be notified of my question, but it's worth a try for me as it is totally impossible to speak to Yahoo grrrrrrr! I have tried to follow your advice, but I've failed at the first hurdle as I can't even delete the yahoo account. I get to the account page through preferences, not settings, so I must have a different version to you, but it won't let me delete the account. So I wondered if you might be able to throw any further light on my plight ha! Thanks in advance....

No, not in admin...

This is the process...

Then it asks for this....

I put the password in and then get this....

So I click either stay verified, or not now. Both have the same result. I then get this.....

to which I put in the code from the authenticator app and then get this....

This happens time and time again, even though it keeps asking me to sign in :(

You absolute legend!!!!!! My ancient 2012 Macbook Pro was fine until I upgraded storage and updated from Mojave to Catalina where I lost my Yahoo mail box and have been using Spark ever since for about a year. So thrilled to have the stock mail app working again, I really appreciate you sharing this solution.

Cheers.

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?

I'm at a loss further. :(

Have you worked it out yet? Very frustrating!

same version same problem. I hope the system doesn't necessitate an iOS update, as I'm concerned it might slow down my laptop.
