Mojave crashes regularly - Coreautha

Hi,

I have the exact same problem as in this post : https://discussions.apple.com/thread/8308370

I have random crashes not specific to a software as this occurs randomly sometimes out of the blue without even using a software.

All of a sudden, I have my finder crashing, my menu bar disappears.

Then a series of popup screens appears asking me for my admin password

accountsd wants to use the "login" keychain

networkserviceproxy wants to use the "login" keychain

com.apple.icloudhelper wants to use the "login" keychain

coreautha quit unexpectedly

I need then to force quit the Macbook pro to restart.

On the restart, I receive a message on my iPhone telling me that my username is now associated with FaceTime and messenger.

Well this happen a lot. I don't really know the frequency every 5-8 days.

I don't know what's going on. Anyone have an idea ?

My setup :

Macbook Pro 15"

3,1 GHz i7

16 Go Ram

SSD 2TB

Mojave 10.14.3
