The first option is more secure. Continuing with the first option above, click Generate app password. Select your email app from the drop-down list, or type it in if it's not listed. Copy the password generated for you. Be sure to copy the password to your clipboard; you won't be able to see it again and will have to generate a new one if you lose it. Click Done and return to your email app to enter the password where prompted. Delete and Revoke an Application Password with Yahoo!
