Most people keep sensitive information in notes apps, spreadsheets, or their memory. None of these are safe. Here's what belongs in an encrypted vault.
What makes something vault-worthy
A vault is for information that is sensitive and not easily recoverable. If it were exposed, it would cause financial loss, identity theft, or significant harm. If it were lost, it would be impossible or very difficult to replace. Notes apps, spreadsheets, and browser-saved passwords fail this test: they're not encrypted at rest, they sync to company servers, and they're accessible to anyone with device access. A zero-knowledge encrypted vault like CiviQ's addresses all three problems.
The threshold for "vault-worthy" is lower than most people think. Any piece of information that could be used to impersonate you, access your accounts, or cause financial damage qualifies. This includes not just obviously sensitive items like passwords and PINs, but also seemingly mundane details like your mother's maiden name, the name of your first pet, and the street you grew up on — common security question answers that together can unlock multiple accounts.
Think of the vault as your digital safe deposit box. Just as you wouldn't leave cash, jewellery, or property deeds lying on the kitchen table, you shouldn't leave digital equivalents in unencrypted apps. The inconvenience of unlocking a vault is the security equivalent of turning a key in a lock — a small friction that provides outsized protection.
Passwords and two-factor authentication backup codes
Login credentials are the most obvious vault item. More critically: store the 2FA backup codes that your accounts provide when you enable two-factor authentication. These codes are the only way to regain access if you lose your authenticator device. They're typically shown once and never again. Most people screenshot them and forget where the screenshot went. Vault them immediately when issued.
The backup code problem is more urgent than most people realise. Your phone — which holds your authenticator app — is also the device most likely to be lost, stolen, or damaged. Without backup codes, losing your phone means losing access to every account protected by two-factor authentication. Recovery processes exist but are slow, frustrating, and sometimes impossible for accounts with strict security policies.
Store each account's backup codes as a separate vault entry, labelled clearly with the service name. When you use a backup code, update the entry to remove the used code. Some services provide one-time codes (each can be used once), while others provide a single recovery key (reusable). Note which type each service uses so you know whether a code is still valid.
Cryptocurrency seed phrases and private keys
If you hold any cryptocurrency, your wallet seed phrase (typically twelve or twenty-four words) is the master key to your funds. Anyone who obtains it can drain your wallet. It cannot be changed, reset, or recovered by any exchange or wallet provider. This is the most critical item to store in a vault and the most dangerous to store anywhere else. The same applies to any private keys used for signing transactions.
The cryptocurrency community is divided on digital versus physical storage of seed phrases. The argument for physical storage (metal plates, paper in a safe) is that it's air-gapped — it can't be accessed remotely. The argument for vault storage is that physical media can be destroyed, lost, or found by others, and a zero-knowledge encrypted vault provides strong protection with better durability and accessibility.
A balanced approach is to store seed phrases in both locations: the encrypted vault for accessibility and convenience, and a physical backup in a secure location for disaster recovery. If you choose vault-only storage, ensure your vault master password is itself backed up physically — otherwise, losing the master password means losing access to the seed phrase, which means losing the funds.
Government identification numbers
Your Aadhaar number, PAN number, and passport number are enough for identity theft in many contexts. They should not be stored in a shared notes app or sent over messaging platforms. Keep them in your vault with a reference to the physical document location. You'll need them for tax filings, account openings, and government services — having them in the vault means you can retrieve them securely from anywhere.
Identity theft using government ID numbers is not theoretical — it's a growing problem. An Aadhaar number combined with basic personal details can be used to open financial accounts, apply for loans, or redirect government benefits. A PAN number can be used for fraudulent tax filings. Keeping these numbers in a searchable, unencrypted format on your phone or laptop exposes them to every app with file access and every person who borrows your device.
Store each ID number as a separate vault entry with the ID type, number, issue date, expiry date (if applicable), and a note about where the physical document is stored. This creates a secure reference that's accessible when you need it for a form or application, without exposing the information to anyone who happens to see your phone screen.
Insurance and financial policy details
In an emergency, you or your family needs to find insurance information quickly — policy numbers, coverage limits, insurer contact numbers, claims process. This information is not sensitive in the same way as a private key, but losing it at the wrong moment is genuinely costly. Store policy summaries in the vault with renewal dates. CiviQ lets you add notes alongside vault entries, making this straightforward.
Create a vault entry for each active insurance policy: health, life, vehicle, home, and travel. Include the policy number, sum insured, premium amount, renewal date, insurer's claim helpline, and a brief note about the claims process (which documents are needed, whether cashless facilities are available, and any waiting periods). In a medical emergency, this information can save hours of confusion.
Consider sharing vault access with a trusted family member for insurance entries specifically. If you're incapacitated, someone needs to be able to find your insurance details and initiate claims. CiviQ's vault supports this through key bundle sharing — you can grant access to specific vault entries without exposing your entire vault.
Bank account details and emergency access information
Full bank account numbers, IFSC codes, and nominee information should be stored securely — both for your own reference and so that a trusted family member can locate them if needed. Store these in the vault with clear labels. Consider writing a brief access guide for a trusted person explaining where the vault is and how to access critical information in an emergency — this is the digital equivalent of leaving instructions in a safe deposit box.
The emergency access scenario is uncomfortable to contemplate but important to plan for. If you're hospitalised, travelling without connectivity, or otherwise unreachable, can your family access the financial information they need? Do they know which bank accounts exist, who the nominees are, and how to contact each institution? A vault entry titled "Emergency Financial Summary" with this information, shared with a trusted family member, provides peace of mind for the entire household.
Beyond bank accounts, include details of any investments (mutual fund folios, demat account details), fixed deposits, recurring deposits, PPF accounts, and any other financial accounts. The goal is a complete inventory of your financial life — not detailed access credentials, but enough information for someone to identify every account and contact the right institution. This inventory is also invaluable for your own reference during tax season or financial reviews.
