Returning users can reverify their identity with a selfie, or move their reusable identity to a new device. Users open Nametag on their phone by tapping a link, with no pre-enrollment or app download needed. Nametag lets organisations send a verification request through normal support channels, prompt it automatically, or direct users to a branded self-service microsite.
