Identity verification through Diia.Signature: real age and real name instead of self-reported ones.
Identity verification through the Diia app. The user signs a request in Diia, we verify the signature cryptographically, and the profile gets a verified name, date of birth and gender. An organizer can require this verification for 18+ events.
For events with alcohol, adult formats or dating, age is not a profile detail but a requirement. The organizer turns on the 18+ label and the verification requirement, and a guest without a verified identity simply cannot register: the check happens before registration, not at the door.
There is a useful side effect beyond 18+: in formats like Speed Dating, verified age and gender make the matching fair.
On AOA, Diia is identity verification, not a way to sign in: you create an account the usual way and add verification to it. We do not sign documents through Diia.
