Abstract
Techniques are described for multi-factor authentication and device verification based at least partly on a periodically changing (e.g., rotating) security code. A rotating security code may be generated on a user device and used to sign a certificate. The certificate may be encrypted, using a private key stored on the user device, and communicated to a backend service for verifying that the user device is authorized to access secure information. The backend service may decrypt the certificate (e.g., using a public key associated with the private key), extract the security code from the decrypted certificate, and compare the extracted security code to a security code associated with the user device. If the codes correspond to one another, the user device may be verified and provided with access to secure information such as secure data, a secure portion of an application, and so forth.
