Unlock What Your Estate Plan Can't

Losing a loved one is an incredibly emotional and stressful experience. It can be all consuming and picking up the pieces is the last thing you want to think about.

But if your partner or a close loved one passed away tomorrow, could you or someone close step into the household within 48 hours and keep things running? Not perfectly. Not permanently. Just enough to make sure the bills get paid, the insurance stays active, and nothing falls through the cracks.

If your answer is somewhere between "no" and "I think so, but I'm not sure," you're in the right place.

Your will covers the legal transfers.
Your advisor covers the portfolio.
Nobody covers the other 80%.

When a partner passes away, the immediate crisis isn't the trust or the will. It's the operational reality: the 50 to 100+ accounts, the autopays tied to a credit card that just got cancelled, the insurance portals with their own rules, the pensions with deadlines nobody mentioned, and the hundreds of hours of administrative work that follows.

The average family spends over 500 hours and $12,500 navigating the financial and administrative aftermath of a loss. Most of that chaos comes from the operational layer that estate plans and financial advisors were never designed to cover.

The companion card cascade. A credit card is cancelled after a partner's passing. The companion card stops working. A dozen autopays fail silently.

The inheritance tax freeze. A bank freezes 50% of a joint account for a state tax waiver. Nobody warned you. Bills are due.

The insurance gap. Health coverage lapses because a required form went to a spam folder. The surviving partner finds out from a letter in the mail.

The locked email. A partner's email is the key to resetting every password. The account has two-factor authentication tied to a phone that's now locked.

Every one of these is a real example. Every one could have been prevented with preparation.

How Prepared Is Your
Household — Really?

Our free 5-minute assessment reveals the gaps between how ready you feel and how ready you actually are. No email required. For the most revealing results, each partner should take it separately.

"The trust covered the legal transfers. The financial advisor covered the portfolio. Nobody covered the other 80%. That's what OneMasterKey is for."

Built From Real Experience

I built OneMasterKey because I wish I'd had it. When my father passed away after battling Leukemia, my parents had a trust, a financial advisor, and even a password list. By most standards, they were organized. It still took me weeks to untangle 90+ accounts, navigate a state inheritance tax hold that froze half their bank account, and redirect autopays after my mother's companion credit card was cancelled without notice.

The trust covered the legal transfers. The financial advisor covered the portfolio. Nobody covered the operational layer: the autopays, the institutional rules, the insurance deadlines, the dozens of phone calls and forms and surprises that come after a loss.

I designed OneMasterKey to be the tool I wish someone had handed me before any of that happened. Not after, when everything was urgent and emotional. Before, when there was time to do it calmly.
