Changing your Yahoo phone number without signing in can be a challenging task, as Yahoo requires user authentication to ensure account security. Nonetheless, if you don't have access to your Yahoo account, there are a few steps you can take:
1. Contact Yahoo Support: Reach out to Yahoo Support directly through their official channels. Explain the situation and provide any necessary information they may require to verify your identity. They may be able to assist you in updating your phone number without signing in to your account.
2. Recover Your Account: If you are unable to sign in to your Yahoo account because you have forgotten your password or lost access to your recovery methods, you can attempt to recover your account. Visit the Yahoo account recovery page and follow the instructions provided. You may need to provide information like your alternate email address or answers to security questions associated with your account. Once you regain access, you can proceed to update your phone number.
3. Verify Ownership through Account Recovery: In some cases, Yahoo may require additional verification of ownership to change your phone number. This process usually involves providing personal information associated with your account, such as your full name, date of birth, and location. Ensure that the information you provide matches the details on record, as it will help Yahoo confirm your identity.
4. Secure Your Account: Once you have successfully changed your Yahoo phone number, take precautions to secure your account. Enable two-factor authentication (2FA) to add an extra layer of security. This feature will require you to verify your identity through a secondary device or app when logging in. Additionally, consider updating your password regularly and selecting a strong, unique combination of characters.
Remember, Yahoo's support channels and account recovery options may evolve over time. It's always best to refer to the official Yahoo support website or contact their customer support directly for the most up-to-date instructions and assistance.
