Logged out from every account

[chaudharyv101]

I restarted my laptop and found out that I was logged out from every account of mine in every app or website I was using.
I am using 2015 MacBook Pro.

I was logged out of Chrome, Safari, Facebook, icloud, Grammarly and what not?
Please help me to know what has happened.

Merely being 'logged out' does not really mean much, and this may have happened as a result of a disconnection or connection reset....

So log back in by entering appropriate username/password for applicable accounts...
