Less secure app blocked

Ive just tried setting up my email notifications from my profilux 3.1 and receive the following message from google. Does anyone know how to resolve this? Thanks

Less secure app blocked
Google blocked the app you were trying to use because it doesn't meet our security standards.
Some apps and devices use less secure sign-in technology, which makes your account more vulnerable. You can turn off access for these apps, which we recommend, or turn on access if you want to use them despite the risks. Google will automatically turn this setting OFF if it's not being used.

Different email providers have different "security standards". You can find instructions for gmail setup here:
