Hi Gurcharan,

Someone just tried to sign in to your Google Account _______________ from an app that doesn't meet modern security standards.

Is their any update that's been pushed to GAE authentication and how to get it work?

Hello Gurcharan,

Since you're authenticating using a username and password, it seems like you may be using ClientLogin which has been deprecated. Please review this doc for information regarding migrating from ClientLogin to OAuth 2.0.

Until your application migrated to OAuth 2.0, you can try allowing less secure apps (turn 'On') although it's not guaranteed to work.
