Sign in attempt prevented

Hi srforce12, Your account is currently not enabled to sign in from apps that do not meet modern security standards (ex. Older versions of mail and calendar apps such as Outlook). As a result, we prevented a sign in to your Yahoo account (srforce12). Date and Time: January 25, 2018 2:41:20 PM PST Location: Vietnam (IP Address: 14.177.151.42) We strongly recommend that you switch to Yahoo's apps such as Yahoo Mail on desktop and mobile and remove your account from all other less secure apps. If you still want to use an app that uses less secure sign in, go to https://login.yahoo.com/account/security#other-apps and turn on "Allow apps that use less secure sign in". This is not recommended and may leave your account more vulnerable to compromise. To learn more, please visit our help page: https://help.yahoo.com/kb/SLN27791.html. Yahoo blocked this sign in attempt, but if it looks suspicious to you or it's not from an application that you're using, go to https://login.yahoo.com/account/change-password and change the password for your account. You are receiving this notification because newarmyguitar24@gmail.com is listed as a recovery email for srforce12@yahoo.com. Thanks, Yahoo Replies sent to this email cannot be answered.
