If you have a free Gmail account and use a Scan to Email app on a Multi-Function Printer (MFP), you'll notice an impact.
Google has announced that as of May 30th, 2022, it will disable control over Less Secure Apps on free Gmail accounts. A Less Secure App (LSA) only requires a username and password to connect to your Google account, and does not use more modern security methods. This change is part of a step-by-step shift to gradually increase Gmail security while minimizing disruptions to end-users.
If you have a free Gmail account and use a Scan to Email app on a Multi-Function Printer (MFP), you'll notice that this function will no longer be available. Other examples of LSAs include Native mail, contacts and calendar sync apps on older versions of iOS and OSX, and some older versions of Microsoft Outlook.
For additional information and guides on how to continue using scan to email functionality after the update goes into effect, please see downloadable documents below.
