Separate yahoo email account from AT&T

Short answer, no.

If you have a Yahoo/AT&T email account (att.net, sbcglobal.net, bellsouth.net, pacbell.net, prodigy.net etc) then it is hosted on the Yahoo servers.  Once past the login, for all intents and purposes you're essentially the same as a yahoo.com email account.

If you unlink your account from AT&T it doesn't do anything on the email side, everything remains exactly the same except that you won't have "support" from any official AT&T people (not that that is a bad thing).

So if I understand correctly, if I change all the login information to websites in which I used my att.net email to login instead with my yahoo.com email, that won't have any effect on my yahoo email account itself. My att.net email will then only get me into my AT&T account?

I'm not following you, sorry.  Can you give me some examples of what you're asking about?

Let's look at your email, @mhthunter.

Thanks @tonydi for the helpful input.

No, changing any sign in information for other sites should not effect your email account. Your AT&T email is tied to your Yahoo email. You can even cancel your account, and keep your AT&T email account. 

What sites are you trying to sign into without your AT&T email? Why is it important you use a different email? Let us know, and we can go a little more in depth.

Actually, I want to get rid of my AT&T email account without losing my yahoo email account. I no longer want to use my AT&T email account to login to various apps and sites. It is confusing to have both email addresses intertwined with each other. 

What is the domain name of your AT&T account (the part after the @ sign)?

There's no connection between AT&T email accounts and your Yahoo email account (one that ends with yahoo.com).  They're completely independent.

att.net follows the @ sign. I don't understand that when I go to the yahoo email login URL, I am directed to sign in with my AT&T email address. I cannot sign in with a yahoo email address. I don't know why can't I sign into my yahoo email account with a yahoo email address and must use the att email address.

The Yahoo sign-in page (mail.yahoo.com) is only for yahoo.com accounts. 

If you enter an AT&T email address in there, it redirects you to the att.com login page.

But if you enter a yahoo.com address at mail.yahoo.com then it should accept that.  It should never re-direct you.

You do have two email accounts, right, like mhthunter @ yahoo.com and mhthunter @ att.net.  (I'm just using those as examples).

Think you've helped me sort this out. Apparently the yahoo.com email addresses I have are disposable addresses I've created within my AT&T account. The disposable addresses allowed in the AT&T account are formed "nickname-[keyword]@yahoo.com." Apparently I have disposable email addresses with the yahoo.com suffix and not a yahoo email account. Does that sound right? Thanks.

Ahhhhh!  Yes, that makes perfect sense now. Any Yahoo-based account can have up to 3 of those.  I don't think I've ever used those, well, because I use "real" yahoo.com email accounts as "disposable" accounts.  😁  But since it's really just an alias of the att.net account, that explains why it logs in that way.

Good catch!
