Loving this new feature found in Version 92.0.873.0 (Official build) canary (64-bit), "Require authentication". This is not a flag, it is just there in "Profiles/ Passwords"
So far I've tested each setting for an hour on each and all works well. At least on my system. This is more than likely a rollout and I'm sure others already have it, but I did not find any mention of it in this forum. Would like to see a couple or so more selections like once every 10, 20, 30, 60 minutes, etc.... At any rate, I love it! Thanks Team!
