The Signal messenger and protocol.

Hi all.

For a long long time I've been very happy with Signal, but have lately become rather annoyed that:

1. it too often bugs me about about an update and forces me to do an update before I can write to my single/only recipient, and
2. it too often bugs me about my pin code, even tho I never asked for such an annoying level of security.

These security measures are completely overkill for my/normal use, unnecessary, annoying and very aggressive. I'm an adult, and unless there's a super dangerous zeroday attack/vulnerability, I don't need constant forced updates, I don't want to retype a pin code for any reason or interval, and I certainly don't need to be told how I should run my system, when to upgrade or have software on my system that 'randomly' gets locked down for whatever reason.

Does anyone know how I can turn it off (Linux, Android) ? Is there another client fork that don't force me to follow their idea of what security level is necessary ?

Thanks, and apols for negativity..
