Systems and methods for single-step out-of-band authentication

1. A method of performing out-of-band user authentication, the method comprising:

by a service electronic device associated with a service:

receiving, from an electronic device, a request to initiate a session of the service,

generating an authentication token,

encrypting the authentication token to generate an encrypted authentication token, and

transmitting the encrypted authentication token to the electronic device,

by the electronic device:

receiving the encrypted authentication token,

retrieving a public key and a private key associated with the electronic device from a data store,

retrieving a service public key from a data store, wherein the service public key is associated with the service,

decrypting the encrypted authentication token using the private key to obtain the authentication token,

signing the authentication token with the private key to generate a signed authentication token,

encrypting the signed authentication token with the service public key to generate a signed-encrypted authentication token, and

sending the signed-encrypted authentication token and a security token to a server electronic device,

by the server electronic device:

receiving a request for the signed-encrypted authentication token from the service electronic device, wherein the request includes a read token and an indication of a memory location accessible by the server electronic device,

verifying that the read token matches information stored at the memory location, and

in response to verifying that the read token matches information stored at the memory location, sending the signed-encrypted authentication token to the service electronic device.

2. The method of claim 1 , further comprising:

by the service electronic device:

decrypting the signed-encrypted authentication token using a private key associated with the service to obtain a signed-decrypted authentication token,
