I have used Macs for many years with no problems. Got a new iMac last January, and although I love it, it has stopped recognizing a couple of my passwords, namely gmail and iCloud. Can’t figure out why. Always happened overnight. I’d shut down in the evening, and next morning upon turning it back on, I had problems. I have no clue!

I have seen the same quark. I turn the computer wifi off and on and the problem goes away.
