How to send the checkup report through your Yahoo! or Google account

Security measures implemented by Yahoo! and Google may prevent your checkup report from relaying through their services until you generate an "app password" through their email account settings.

Yahoo! settings

If you've activated two-step verification or Account Key for your Yahoo! account, you'll need to generate and use an "app password" to allow the software to access Yahoo! Mail. Please refer to the Yahoo! kb for steps to resolve the matter. Currently the kb is at https://help.yahoo.com/kb/SLN15241.html.

If you have not activated two-step verification for your Yahoo! account, you still may have to enable "Allow apps that use less secure sign in".

Google settings

If you've activated two-step verification for your Google account, generate and use an "app password" with your account. Please refer to their kb for steps to resolve the matter here: https://support.google.com/accounts/answer/185833?hl=en&ctx=ch_DisplayUnlockCaptcha
