Reason is that the Security Setting "Allow apps that use less secure sign-in" does not exist anymore.

For gmail it is required to activate the option "Allow apps that use less secure sign-in" to be able to conduct the following steps of the instructions. This hint is missing.

A proposal from "greg at kroah.com  Sun Dec 27 03:50:21 2020" proposes to use fastmail.fm
fastmail.fm is not for free and also not mentioned in the "FirstKernelPatch" instructions.

Please do not let all newbies fall into this trap.

Please provide me a login or edit yourself.

Thanks for your support.
