everytime i go to yahoo mail, a message appears saying " safari cant verify the identity of login.yahoo.net". Did anybody encounter the same problem? I have been opening yahoo mail without this problem.

True. But that was in 2002. Not sure that I would want to trust that it's still the same entity operating under that name without further evidence.

Did some more investigating. The login.yahoo.net appears in a link in the body of the page:

https://login.yahoo.net/login_superads/us/superads_iframe_content.html...

Loaded the page in Firefox with Firebug on. No error message. Firebug lists the https://login.yahoo.net/... request, with status aborted. Seems the underlying cause is present in both, but the browsers respond differently.

The main page is https://login.yahoo.com/config/login_verify2?&.src=ym, on the login.yahoo.com domain. Only the embedded ad is on the .net domain and has the domain mismatch. So it seems to me that we can click cancel on the error message to abort loading the ad, and then login as usual, in effect doing what Firefox is doing.

I'm not trying to sell you on the idea of trusting the certificate. But the host output is correct. I get the same thing.

From what I can comprehend in all the answers here, I think maybe it's looking safe to log in? FWIW, Last night I tried on a 3 year old Compaq Presario notebook with Windows Vista Home Premium and I didn't get the warning message at all. So maybe it's a Mac problem only, or my Windows notebook isn't set up to warn about that but highly doubt it, will look into that though.

Ok, and if it is a serious hack, what do we do..... not a techie here! It is also happening with Windows7 on my laptop using IE. Want to be sure I understand... you think this is coming from and ad that is trying to display????

Forgot to mention, the Windows browser I used is Firefox 3.0.13.

I'm still not feeling good about this. I get the message on my iMac, but not on my Macbook Pro. On the iMac I get it from Safari running under Mac OSX, and also from Chrome and IE running in a Windows 7 partition under Parallels. Maybe it's just Yahoo dicking around with trying to force people to see advertising for their Facebook link or whatever, but address re-routes make me nervous.

Wish I could edit here. Realized my WIndows Firefox was old so just updated to latest version 5.0.1 and still get no error/warning like I get on my iPad.

also: this morning, after having no hiccups in mail delivery via my iPhone yesterday, this morning I got a popup saying that I had no password entered in the iPhone mail setup on one of my Yahoo email accounts; somehow the password was deleted from yesterday to today? It happens to be the email address I used when submitting a problem report to Yahoo about all of this yesterday morning; wonder if there is any connection there.

does anyone have any thoughts about whether it's safe for me to put in my password on my iPhone so I can get mail from that acct?

Tried the iphone and/or ipad forums?

also, malware on smart phone devices along with how to protect your device and information along with pswd. Not just an issue on Android devices.

I am having same issues here with my iPhone. The password disappears from my yahoo account setup. But only for one of my accounts. My second account has no issues. The same is happening on two of my computers. Both on IE and Firefox. The password is "forgotten" from my pc/iphone. Maybe something is erasing the cookie (cache file containing the pw) ? Dunno but this is really annoying now. May be with yahoo where the problem is. But is hard to get a hold of anyone there to even explain the problem.

I have changed my pw twice this morning because I thought someone had hacked my pw. But is hard to verify the new password since as soon as I login, the pw disappears forcing me to login again.

All this issues with yahoo today forced me to setup another account with gmail on my iphone. NO issues login on to it from iphone or pc.

The problem seems to have disappeared ... I guess Yahoo did something.

check your date and time settings. make sure the hour, time, and year are set correctly.
