FAQ

Documentation
What if I lose my phone?

Restore your recovery phrase in the Vaultum phone signer, then pair again. Freeze the vault from your wallet while you recover. Never enter the phrase in this dashboard.

What if I lose my recovery phrase?

An unlocked signer can still approve requests. If you lose both signer access and your phrase, the signing key cannot be recovered. Rotation does not replace a lost backup.

Can I sign without a phone?

Yes. Choose This browser when creating a vault. Its key is encrypted with a passkey or passphrase. It protects against quantum attackers and stolen wallets, but not malware on this computer or a compromised dashboard. The signing location cannot be changed; create a new vault to move.
