Spring cleaning around here usually means the gutters, the woodpile, and whatever the winter left in the yard. Your accounts and devices deserve the same treatment, and it takes one afternoon.
Close the Accounts You Forgot About
Every account you no longer use is still holding your email address, maybe a card number, maybe an old password you've reused elsewhere. It's sitting there with nobody watching it.
Search your email for "welcome to" or "confirm your account" and you'll find years of them. Delete the ones you don't want, and don't just abandon them—an abandoned account is still a live account.
Audit the Subscriptions
Check the subscription list in your phone's app store and your card statements for the last few months. Recurring charges are designed to be easy to start and forgettable afterward.
Cancel what you don't use. This one usually pays for the afternoon.
Look at What's on Your Network
Open your router's admin page and find the list of connected devices. Most people find something they can't identify, and it's usually not sinister—an old tablet in a drawer, a printer nobody prints to, a streaming stick from two TVs ago.
Anything you're not actually using should come off the network. A device that hasn't been updated in years, still logged into your accounts and sitting on your Wi-Fi, is a loose end with no upside. Powering it down or removing its Wi-Fi access is a two-minute job.
Deal With the Reused Passwords
This is the item people skip, and it's the one that matters most. If the same password opens your email, your bank, and a forum you joined in 2014, one breach anywhere unlocks the set.
We won't relitigate it here—we made the whole case in Password Managers Are Worth It. If you read that post and meant to get around to it, this is the afternoon. Start with email, then banking, then anything holding a card number, and let the manager handle the rest as you go.
You don't have to finish all four in one sitting. Pick the one you've been avoiding longest and do that.
