Netgear account login problems on iPhone

I have an issue where when I try to login to my Netgear Account on my iPhone with safari I get an error or incorrect email or password, I have then been forced to change my password several times to fix this. Then I tried to login with my laptop and an iPad and works fine, just my iPhone will not allow me to login. Called Netgear who were no help at all. Anyone else have these issues? And I have cleared all cookies and history and still have same problem?!
