E mail explanation wanted

[davyboy 19]

I have 3 e mail addresses 2 of which are g mail and yahoo mail.

I access them by opening Safari (I have an iMac) and logging into google and yahoo and then clicking onto g mail and yahoo mail.

Until recently, when I had problems having changed my yahoo password, I could also access my 3 e mails through Apple's MAIL.

Now not only does MAIL not inform me that I have x number of e mails waiting but if I try to get my yahoo e mails it keeps asking for my Yahoo password.

I type it in,it's not accepted even entering it again.(nor the old p/w.)

There are solutions given byApple:

https://discussions.apple.com/thread/4478295?start=15&tstart=0 which I cannot understand so it's not just me who has this problem.

I have just remembered I turned on the 2 step activation but then turned it off.could this be the reason?

 

Can anyone help?

The most obvious reasons are:

 

Yahoo mail is not allowed POP access

Yahoo mail is allowing POP access but you haven't enabled it on the Yahoo web mail configuration

Yahoo mail is allowing POP access but your username or password is wrong on Apple Mail

problem solved. i went into yahoo via system preferences and was given a account key 16 low case letters.Entering this p/w allows me to get yahoo e mails via apple mail.

Let's hope it doesn't reoccur.
