Hey Yahoo Member,

Head’s up: As of 20 October 2020, Yahoo Mail will no longer support third-party applications (such as third-party email, calendar, or contact applications) using outdated sign-in methods. That just means if you’re still signing in to your Yahoo account via another email application, like the default email application on your phone, you need to make some quick updates to ensure your mailbox isn’t interrupted.

Here are your options:

Option 1: We recommend that you access your email using our free Yahoo Mail app for iOS and Android or simply go to mail.yahoo.com to access Yahoo Mail on the web.

Option 2: Keep your current, non-Yahoo app, BUT follow a few steps to get it to sync with our secure sign-in method. The steps vary across different email applications, but in most cases, you will have to remove your Yahoo account from the app and then add it back again to update the sign-in security. Use the links below to follow the specific steps for your current application:

    iOS Mail
    Gmail
    Samsung Mail
    Others


Option 3: You can generate a one-time, unique password that will allow you to sign in to your account using your non-Yahoo email application. Once created, this password will continue to allow your app to securely sync your Yahoo email unless you sign out (or are signed out) from your app. You can find instructions on how to do this here.

Questions? Please visit our help page. If you’ve already made the necessary changes for your account, we appreciate the quick action!

Gracias por contestar y por tu aportación.  Me podrías ayudar con la sintaxis del programa, porque no me queda nada claro como implementarlo, entiendo lo que se expone pero no sé como aplicarlo en java

intente con eso pero no era la flag ¿con que decifreaste el mensaje?
 gracias amigo
