To log in to Yahoo Mail without a verification code, you can use alternative recovery methods or disable two-step verification. After entering your Yahoo email and password, if prompted for a verification code, click “Try another way” and select options like receiving a code via a recovery email or phone number. If you don't have access to these, answer any security questions you've set up. To avoid future verification codes, you can turn off two-step verification in the "Account Security" section of your Yahoo account settings. Be aware that disabling this feature reduces your account’s security.
