Android yahoo mail authentication failed

Frustrating!

When you encounter "Authentication failed" error on Android while trying to access your Yahoo Mail account, it's usually due to one of the following reasons:

  1. Incorrect login credentials: Double-check your Yahoo Mail login credentials, including your username and password. Make sure you're using the correct login information.
  2. Outdated app: Ensure you're running the latest version of the Yahoo Mail app on your Android device. Update the app if necessary.
  3. Server-side issue: Yahoo Mail servers might be experiencing technical difficulties or maintenance. Try restarting your device and retrying to access your account.
  4. Two-factor authentication (2FA) issue: If you've enabled 2FA on your Yahoo Mail account, you might need to enter the verification code sent to your phone or authenticator app.
  5. Account lockout: Your account might be locked due to too many incorrect login attempts. Try waiting for a while and then retrying to access your account.
  6. App permissions: Ensure that the Yahoo Mail app has the necessary permissions to access your account. Go to your device's Settings > Apps > Yahoo Mail > Permissions and grant the required permissions.
  7. Cache and data issues: Clear the app's cache and data to resolve any temporary issues. Go to your device's Settings > Apps > Yahoo Mail > Storage > Clear cache and Clear data.
  8. Account settings: Check your account settings to ensure that your account is set up correctly. Go to the Yahoo Mail app > Settings > Account > Account settings and verify your account information.

To troubleshoot the issue, you can try the following steps:

  1. Restart your device and the Yahoo Mail app.
  2. Check your internet connection and ensure it's stable.
  3. Try accessing your Yahoo Mail account using a web browser (e.g., Google Chrome) to see if the issue is specific to the app.
  4. If you're using a VPN, try disabling it and see if the issue persists.
  5. Reach out to Yahoo Mail support for further assistance.

If none of these steps resolve the issue, you can try resetting your Yahoo Mail account password or seeking help from Yahoo Mail's customer support team.
