Nah. The need to regularly change passwords is unnecessary. If you use a sufficiently long password, unique passwords for every site, and 2FA/MFA for “important” logins, then you’re good.
Businesses requiring their staff to regularly cycle passwords is outdated and makes their systems less resilient, since it opens more angles for social engineering attacks or password security carelessness.
Depends on the item and your goals.
If you’re a “car person” who always wants to have the latest model, then maybe leasing a car makes sense. Every 3 years, you get a new car.
Phones are similar; there are some plans where you are expected to return the phone every 1-2 years. If you really want the newest model all the time, then that might be a good plan for you.
But for a printer, that only makes sense if you’re a business with medium print volumes and no IT budget. For home use, that’s insane when a cheap last printer will last decades. We have a B&W laser from 2 decades ago and a used colour laser we got for free/very cheap (the power button is broken but it otherwise works great). I’m guessing we pay about 1-2% of an HP subsription.
