Using Techtool Protection, you can get email notifications if SMART is failing or a drive becomes too full. If your email provider requires two-factor authentication, you may need to set up an app-specific password in order for email alerts to function properly. Here are instructions for commonly used email providers.

iCloud

First, you'll want to log into your Apple ID account at https://appleid.apple.com and access your iCloud settings. (If you have to get a message on your phone or iPad before logging in, this confirms that two-factor authenticaion is enabled.) Click Edit for Security Settings, and then click on Generate App Specific Password. Create a password, and name it something that will remind you that it's for Techtool Protection. Copy that password and paste it into the Password field in Techtool Protection's email alerts password field. This should allow email alerts to send emails, provided the remaining settings are correct.

Gmail

First, you'll need to log in to your Google Account at https://myaccount.google.com. On the left navigation panel, click Security. Then, on the Signing in to Google panel, click App passwords. Click Select app and choose 'custom,' enter 'TechTool Pro' then click Generate. Follow the instructions to enter the App password (the 16 character code in the yellow bar) on your device. Click Done. Once you are finished, you won’t see that App password code again, so be sure to save it securely, in case you need it in the future. You can then use this password to allow email alerts from Techtool Protection, provided the other email settings are correct.
