Can't acces Google security account because of my old smartphone's Android 6.0/ Can't add my google mail account to em Client.

Initial setup
1

To add my google mail account to em Client I’m asked to enter a security code which I would receive through my smartphone. However, my smartphone doesn’t have this feature since it is an Android 6.0. It’s only with Android 8.0 that you get this function.
Since there is no other option to verify my google mail account for em Client, I can’t add my google mail account to em Client.

Is there anything I could do so that I can finally add my google mail account?

This is something you need to change in your Google security settings, which you will find at https://myaccount.google.com/intro/security.
