Safely sharing passwords with family (and why a notebook fails)
Léon van Leeuwen · November 7, 2025

It is a classic dilemma. You know your partner or a trusted family member needs access to your most important accounts "just in case". But how do you arrange that?
Most of us fall back on DIY methods. A notebook in a drawer. An Excel file on a USB stick. A 'secret' note on your phone.
While well-intentioned, these methods are impractical at best and downright dangerous at worst. Let's be honest about the risks and discuss the only solution that is really safe.
The dangers of the DIY password vault
The methods used by the vast majority of people fail on three crucial points:
- They are physically vulnerable: A notebook in a drawer is vulnerable to fire, water damage, or theft. A single break-in and a thief has the keys to your entire digital life.
- They are digitally insecure: An Excel file (even password-protected) or a note in your email is a massive risk. If your computer or email account is hacked, the hacker has direct access to all your accounts. You have just handed it to them on a silver platter.
- They are always outdated: This is the most common problem. You change your bank password, but you forget to update it in that notebook or file. The moment your family needs it, the information is useless and they are still left locked out.
A password manager to the rescue?
A password manager is a much better idea. For daily use, it is an incredibly secure way to manage your passwords and login details. However, a password manager essentially gives your family a dictionary (a list of data) without context. What they need is a guide (a roadmap with instructions). The "emergency access" does not solve the problem; it creates a new, overwhelming burden.
The only truly secure way: Zero-Knowledge encryption
To safely share passwords with family, you need a system built specifically for this purpose. The gold standard for this is called a "Zero-Knowledge" Architecture. And that is precisely the technology Veault is built on.
- What it means: 'Zero-Knowledge' is a technical term for a simple promise: we cannot read your data. Even if we wanted to.
- How it works: As we explain in this article, your passwords are encrypted on your device before before they are sent to our servers. Only you hold the 'key' (your master password). We only store an unreadable, encrypted vault.
- The Analogy: Think of it as a physical vault. We sell you the vault, but only you know the combination. We cannot open it for you.
More than Secure: Make It Usable
If you already use a password manager, you can share the login details for this password manager with your loved ones in your Veault vault. If you do not use a password manager, we give you the option to store your most important login details directly in your vault:
- Item: Netflix
- Password: [your-password]
- Instruction: "Please cancel. Linked to my PayPal account."
- Item: Child's Savings Account
- Password: [your-password]
- Instruction: "This is the savings account for [Child's Name]. This must continue until their 18th birthday."
Conclusion: Stop writing notes, start with a plan
The 'just-in-case' plan for your family is too important to leave to a notebook. You need a system that is secure, always up to date, and, perhaps most importantly, clear and actionable for your loved ones.
Sharing passwords is an act of trust. Make sure you have a system that earns that trust.
