Planning for lost or shared access

Planning for lost access starts from a plain fact: on a self-custody wallet, the recovery phrase is the account. If the only copy sits in one drawer and that drawer is lost in a fire or a move, the funds are unreachable for everyone. A plan names where each backup lives, who knows the places exist, and how a backup is tested without exposing it. Many people keep two copies in separate locations and record, in a separate note, only the location rather than the words. Custodial accounts need planning too, since recovery depends on the identity documents, email address and phone number the company has on file, and those change over time.

Shared access is a second question, and there are several designs. A multi-signature wallet needs approvals from more than one key before funds move, so no single device or person can act alone. Some wallets offer recovery through chosen guardians, who can help restore access without holding the full key. Others rely on a written letter of instruction that tells a trusted person where backups are and what to do, kept apart from the secrets themselves. Each design adds moving parts that must keep working for years, and each handles the death or illness of a key holder differently. Review the plan whenever a device, a phone number or a person in it changes.
