Once a user has created a embedded wallet, when they attempt to use the wallet on a new device, the key material for their wallet must be provisioned on that device. In most cases, once a user authenticates on a new device, Privy automatically orchestrates reconstitution of the key material for their wallet on that device. This requires no additional action from the user and allows them to seamlessly use their wallet on any device where they are authenticated. In self-custodial setups, you can also require users to input a password or authenticate with their cloud account (iCloud, Google Drive) in order to reconstitute their wallet on a new device. Follow the steps below to enable this setting.
Additional authentication factors for device provisioning can be reset on a provisioned device, but if a user loses all provisioned devices and their additional factor, they will be locked out of their account.Read more more about Privy’s self-custodial architecture.
