What KEYRA does
Your app requests verification. KEYRA orchestrates the verification challenge. The user completes verification on their device. Your backend receives a trusted authentication result you can enforce.

KEYRA is not a full replacement for every login system by default. Most teams either use KEYRA for passwordless OAuth-based authentication, or add KEYRA as a second factor on an existing login.
