Google to end support for signing in using Less Secure Apps.

This article describes the impact on Dolphin Guide (legacy), and Dolphin GuideConnect, following Google’s announcement that support for apps requiring less-secure sign ins will be ending.

Google has announced that it will end support for less-secure apps from June 2022. This announcement has been sent to many Gmail users running dolphin products:

"On May 30, you may lose access to apps that are using less secure sign-in technology. To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0."

Below we describe what the likely impact on Dolphin products will be:


GuideConnect users with Google Mail accounts, should experience no issues or disruption to service, as GuideConnect requires secure forms of verification in order to add a Gmail account into the product. The option to “Allow less secure apps” is not required to be turned on for GuideConnect to work.

Guide v9 or earlier

Guide version 9 and earlier is considered a “less secure app” by Google, as in order to add a Gmail account into the product, this can be done solely with a username and password. The likely result of Google’s proposed changes, is that users of Guide 9 and earlier will no longer be able to access their Google email accounts in the product anymore. The recommendation would be to upgrade to GuideConnect in order to continue doing so.
