Methods, systems, devices, and apparatuses for passkey authentication at an identity management platform are described. In accordance with the described techniques, an administrator of the identity management platform may enable passkey authentication for clients of the identity management platform. Once the passkey authentication is enabled, the identity management platform may display a passkey login option to users associated with the clients of the identity management platform. If a user associated with a client of the identity management platform selects the passkey login option, a device associated with the user may generate a passkey that includes a private key and a public key. The device may store the private key and transmit an indication of the public key to the identity management platform. The identity management platform may use the public key to verify the identity of the user in subsequent login attempts.
