Every Tuesday morning I have to re-authenticate the 2FA that lets me connect to various things at work, and it isn't documented anywhere, but you'd better believe I figured out the pattern real fast. Being annoyed at the same time of the work week is very noticeable.
I have a Google Hangouts Tuesday mornings. Once a month, reliably, I'd suddenly be kicked off my own Hangout because Google has decided it's time for me to type my password back in.
Of course I do, reliably pushing the problem another month down the road.
