Security verification on a mobile device
To protect your account from unauthorized access sometimes Yahoo will ask you to confirm your identity. You'll need to verify your identity in a web browser before you can add your Yahoo account to your mobile device's default mail app.
Verify your account by receiving a code
- Open a web browser on your mobile device and sign in to your Yahoo account..
- Tap Receive code.
- Select By phone or By email.
- Tap Receive code again.
- Check your email or mobile number to get the code, and enter the code in the "Verification code" box.
- Tap Verify code.
Now that you've cleared the verification prompt, add your Yahoo account to your mobile device.
