If you stop using Vautir
After 3, 6 or 12 months without any of your devices checking in, Vautir sends three check-ins a week apart, then tells your contacts they may ask. They still ask and wait.
Name the people who should inherit your vaults. If they ask, you have time to say no. If you can't answer, they get exactly what you chose, and nothing more.

Pick a contact, the vaults they'll get, and how long they must wait: 7 to 90 days.
If the time comes, your contact asks for access. You're told by email and in every app.
Deny the request any time during the wait. If you don't, they get view access to the vaults you chose.

A special item for the people who get your vault: what to do with each account, and anything else they should know.
Your contact's key is checked against Vautir's key transparency log, and you compare fingerprints once, so no one can slip in their own key.
Free includes one legacy contact. Premium and Families include more.
