BT Yahoo email login fails
Today my BT Yahoo webmail login fails to authenticate my credentials with the message "Please check you entered your username and password correctly and try again." It worked fine yesterday. I tried it on Edge and Chrome and it works fine on both. What has changed since yesterday?

Hello....
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.
