iOS - Yahoo Related Issues

I updated my iPhone 6 to iOS 8.0.2 and I lost both Yahoo inbox mail and also Yahoo Contact.

Apparently for people using second sign-in verification on Yahoo account, the regular password does not work. You have to use a one time password that is generated by Yahoo. These are the steps:
A. Use CardDav Method

1.     Tap the Settingsicon on your device's Home screen.

2.     Tap Mail, Contacts, Calendars.

3.     Tap Add Account.

4.     Tap Other.

5.     Tap Add CardDAV Account under "Contacts."

6.     Enter your:

     ·         Server (https://carddav.address.yahoo.com)

     ·         Yahoo ID

     ·         Password  (PLEASE DO NOT USE YOUR REGULAR YAHOO PASSWORD!!, PLEASE GO TO STEP B FOR THIS PASSWORD)

     ·         Account description

7.     Tap Next to complete set up.

It will take about 2 minutes to process then it would give you this window: Failed to process using SSL. Do you want to continue not using SSL?
I clicked continue and then it was success

B. To generate App Password. You have to login to your Yahoo account setting as follow:

Generating Yahoo App Passwords

To protect your account, you're required to generate a one-time password, separate from your Yahoo account password, when you use non-Yahoo apps.

Here's how:

8.    First activate second sign-in verification on your account to use App Passwords.

9.    From your Account Info page, click App Passwords.

10.  Under "Generate new application password," enter the name of the app that requires a password.

11.  Click Generate Password.
Tip: This isn't a new password for your account. It's a one-time password to validate you're authorizing access to your account from a non-Yahoo app.

12.  Enter the code into the password field of your mobile device.

13.  Click Done to reset the code generator.
-If you forget the code, you can always generate a new one.

You're now safely connected!

We'll save a list of apps within your "Generate app passwords" page. Also from this page, you can generate a new code or  remove permissions.

Hopefully this would help you fix the contact sync problem.

As at this moment I am still not able to get my Yahoo Mail sync to my iOS 8.0.2 Mail App. It was able to get the mail on the other folder, but inbox is EMPTY.

So somehow the inbox folder is totally BROKEN. Anybody can help me with this?

While waiting for the fix, I am temporarily using Yahoo Mail App which you can download it from Apple store.

Please help if you can sync Yahoo Mail.
