Yahoo mail, hackers, iPad and iPhone

[Skyedriver]

Once again a family computer problem I'm afraid.

Wife seems to get the occasional email which claims to be from me but has a spurious email address so obviously dodgy.

Question 1: is that because my yahoo mail or her yahoo mail has been hacked?

She received one today which is giving problems. She didn't open anything, and she's gone in and changed her log in details.
She can now open her emails on an iPhone but trying to log into her emails on the iPad is trouble. Inserts her address and new password and it then says a 6 digit code will be sent to her iPhone. Within a few seconds a code arrives but from what looks to be a random mobile phone number. Ignore that and a few seconds later a code comes from Yahoo.
Transfer the code to the iPad and wait. After a few seconds the message "safari cannot open the page as there are too many redirects"

Been through this countless times, tried Googling remedies on my Windows laptop but the problem persists.

Apparently all iPads etc run Safari, when you click Safari it takes you to Google?

Question 2: How do we return to normal and get her emails showing on her iPad.

Question 3: both her and I have been with yahoo for decades. Is it time to change?

I'm Windows and Android, my son has an iPhone, uses Windows on his PC but uses another email not yahoo.

Thanks everyone.

Probably not hacked, but your email addresses could've been involved in a data leak. Checking here would be a good idea: https://haveibeenpwned.com/

Might be worth installing the Yahoo Mail app from the App Store and seeing if you can gain access that way.

I still use Yahoo Mail, I don't have any issues with it so I can't see a reason to change. However, I access it via its dedicated email app, plus I have multi-factor authentication set up for my account via an authenticator app. Yahoo's text-message MFA has been rather flaky in the past, so I wouldn't rely on that alone.

Thank you for your quick reply.
Son busy deleting the icon for Yahoo that takes her to the web version and installing the App from the App Store.

Puzzled by the Yahoo 6 figure code from a (dodgy?) mobile number on previous attempts to log in.

Update: The App now installed and working, didn't need a 6 digit code as he did "push notification" which apparently opens up on the iPhone App version.

Comment from wife:
she always seems to get problems like this after ordering dog food from "Pooch & Mutt" and they use DPD who subby up here to a local delivery company.

A Google search (AI info?) suggests that none of these have suffered any data breach.
