None of the individual habits in this checkup are complicated. What makes them effective is doing them together, once a year, rather than never doing them at all because no single one feels urgent enough on its own.
Why yearly, specifically
Monthly feels excessive for most of this, and "whenever I think of it" tends to mean never. A fixed annual date is frequent enough to catch problems before they become expensive or risky, and infrequent enough to actually stick as a habit rather than becoming one more thing to feel behind on.
Subscriptions
Review the last three months of bank and card statements for recurring charges you no longer recognize or use.
Check app store subscription pages for anything that's quietly renewed since last year.
Cancel anything you can't remember using in the past six months.
Passwords
Check your password manager for any weak or reused passwords it may have flagged over the year.
Update the password on any account holding financial or highly personal information if it hasn't changed in several years.
Confirm 2FA backup codes are current and stored somewhere you can actually find them.
Access and accounts
Check which apps and services have "Sign in with Google/Apple/Facebook" access to your account, and remove anything you no longer use.
Confirm your legacy or emergency contact settings are still set to the right person.
Delete accounts you're confident you'll never use again.
Tying this review to something already fixed in your calendar — a birthday, New Year's, tax season — makes it far more likely to actually happen every year, compared to relying on remembering an arbitrary date on its own.
