Solution : Allowing less secure apps to access your account

Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safe.

Some examples of apps that do not support the latest security standards include:

Some Desktop mail clients like Microsoft Outlook, Mozilla Thunderbird and  Dreammail.

Change account access for less secure apps

To help keep Google Apps users' accounts secure, we may block less secure apps from accessing Google Apps accounts. As a Google Apps user, you will see a "Password incorrect" error when trying to sign in. If this is the case, you have two options:

Option 1: Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.

Option 2: Change your settings to allow less secure apps to access your account.

Go to the "Sign in & Security" section in My Account, Then in Password & Sign-in Method - Turn Off 2 step verification.
