Google phases out Less secure apps

There is a recent update from Google that As of May 30, 2022, the usage of any third-party devices or apps that allow signing in with only the username and password will no longer be supported.

This update is to permanently block the sign-in attempts from some apps and devices that are using the Less secure app option by using the username and password directly.

Applications that are less secure don’t make use of modern security standards and thereby compromise the security of accounts and devices. So, it makes it easier for the hackers to get into the user accounts. Therefore, only blocking the sign-ins from the less secure apps will help in keeping the accounts safe.

For these reasons, Google is now going to completely disable the ‘Less secure app access’ setting in the Admin console from this May 30, 2022.

This unavailability of the Less secure app enforcement setting option will also have an impact on the SMTP server configuration process. Before knowing more about this, it is much important to know about SMTP and the significance of its configuration process for your website.

So, the SMTP server configuration will ensure the proper delivery of emails from your website to your users’ inboxes so that those emails will not end up stored in the junk mail folder.
