I can't add my Yahoo email account into my iPhone

Re: Sorry i have no idea what that means?

Looking through Yahoo's online "help" seems there may be an extra security requirement when using older software

https://au.help.yahoo.com/kb/new-mail-for-desktop/securely-access-yahoo-mail-sln27791.html

says:

"If you try to use Yahoo Mail in a third-party email client using less secure sign-in technology, you might get a "Server password has changed" or an "Authentication failed" error message. This is because those email apps use outdated security protocols and access to Yahoo Mail is disabled to them by default".

Ie: The older Mail app on your Mac can not securely access your Yahoo Mail (unless)

The answer seems to be to obtain a special app-specific password from Yahoo to allow the Mac's older Mail app to access your Yahoo Mail account.

"The app specific-password gives a non-Yahoo app (Mac Mail 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."

This is the page (NB: for my country 🇦🇺) where you can generate that special password by clicking a link on the Yahoo web-page:

Use an App Password for Login:

Mail is a third-party app. So, use an App Password. Create a unique one for each device. Remove the current one, and then use the new one instead. Sometimes, changes (i.e. updates) are made to the device, and then mail server syncing becomes an issue (which is what a new App Password it intended to fix).:

Yahoo: Generate and manage third-party app passwords | Account Help | Yahoo

yahoo uses safari as the default browser on the iphone. it caches your login and will cause problems. go clear your safari cache by going to: settings, safari, clear history and website data, and choose last hour. now add your yahoo account and it will prompt you for your email and password. it will fail, and you will need to login again in the same browser screen you are in. once you do this it links the account partially. now close this all out, go back to the yahoo app, and add the account. it will now add your yahoo email to the yahoo iphone app. Unreal.

This will allow you to also add sub accounts one at a time, and you need to clear the history each time you add a sub account.

the reason for this odd behavior is that the yahoo iphone app is using the safari browser as a middleman piece of software to marry the app to your email account, and most likely, the cookies have a timeout cache of less than an hour that is causing issues.

Re: "it takes me to the yahoo sign in page where i enter my username and then password... whereupon it ought to then take me to my email account... but it doesnt",

and

"When i go to settings to look at what accounts are there, it has not registered that i have loaded an email account. The phone refuses to register that i have done anything at all, its as if i never signed in".

Seems your older Mac software is not secure enough to allow the Mail app to load on the iPhone, without the extra measure of that secure one-time password giving permission.

ie: seems the secure access to your eMail account requires the verification that your iPhone is in use by you, the account holder (ie: is not somebody else).

Sorry that I do not have that iPhone model and iOS version handy to experiment and outline every step of the process, of getting that one-time password from Yahoo and entering it in the correct place, where the iPhone can gain access to the Yahoo Mail.

Best I can do is to point you to the beginning of that process (repeated below)

This is the page (NB: for my country 🇦🇺) where you can generate that special password by clicking a link on the Yahoo web-page:

(Eg: It is likely you will get an eMail from Yahoo with that special one-time password ... and instructions where to enter it, yet could be a different method.)

Hi HummingbirdBlue

welcome to the Apple (user-to-user) Community.

Re: "iphone 6 (plus) wont load yahoo email account"

Restarting the phone was a great thing to try ... that deletes temporary files and will often restore order.

For iOS 12:

If needed: You can check you are connecting to the Internet ok ...

Connect iPhone to the Internet - Apple Support

For adding the eMail account:

You can quit the Mail app, and restart the Mail app again.

How to: Quit and restart an app on iPhone - Apple Support

Then try again to add the eMail account.

Now I don't know if this will help, or if this is precisely what you have already tried.

For iOS12 :

In the Settings app:

Choose Mail > Passwords and Accounts > Add Account > Yahoo

Add the log-in info, and follow instructions to add the account.

All the best :-)

Thank you kindly for your thoughtful reply, HummingbirdBlue.

A thought just "strucK" ... wondering if you need to log-in to your Yahoo account online, and ensure any boxes are ticked to allow the two-way exchange ...

Yahoo advertise an app that can be used for access to email... have no experience to offer with that though.

If the internet connection is working ok on the iPhone:

As the emails from Yahoo to your phone seem to be getting through on your laptop:

Wondering if you might want to try quitting and restarting the iPhone's Mail app:

If the Mail app still does not receive the eMail from Yahoo:

says:

"Press and hold the side button until the power-off slider appears.

Drag the slider, then wait 30 seconds for your device to turn off.

To turn your iPhone back on:

press and hold the side button until you see the Apple logo."

Check to see if the Mail app is getting the messages from Yahoo now.

However if you scroll down on this page, Yahoo calls it "Apple Mail".

Remove your Yahoo account and re-add it to the Apple email app on your mobile device. When you re-add the account, look for the Yahoo provider logo to trigger the secure sign-in method.

Thank you for your reply, and your patience. Seems the link you followed was quite different from obtaining the one-time password. This one-time password was to permit the Yahoo account to be used in Apple's Mail app.

I may be wrong, perhaps you tried both links.

It seems from your post that the link you followed was for a third-party app password. (You discovered that the third-party (Yahoo) app could not be used on your device.)
