My wife has a touch of OCD. When we are traveling, she will close the hotel door. Then check to see it is locked. Then invariably, she will go back 5 seconds later to check it again.
When shopping, after using the remote to lock the doors of the car, she will walk about 40 feet away, and then return to check the doors again (all the doors, not just one).
Weird, compulsive and annoying.
But in the online world, she uses weak passwords (about 4 of them) and repeats them everywhere. Can’t remember anything really difficult, so they are rediculously predictable.
I bought her 1Password, and have tried to teach her how to use it. Can’t get it. She must have 50 saved logins for her online banking site. Sigh.
