To sign in to Yahoo Mail without needing a verification code, follow these steps:
Use a trusted device: Yahoo may recognize devices you've previously logged in from, allowing you to skip the verification process.
Save login details: Ensure your browser or password manager saves your username and password for easy access.
Enable "Stay signed in": When signing in, check the box to remain logged in, avoiding the need for verification on subsequent logins.
Disable two-step verification: If you’ve enabled two-step verification, consider turning it off through the "Account Security" section in Yahoo settings.
