Electronic signature security algorithms

摘要

Technologies are generally described for security algorithm methods in authorizing and linking devices associated with a customer. A first device can be linked to a customer account. Additional devices can be linked to the customer account. Those devices can be authenticated to perform banking operations using dual factor authentication wherein a customer's login information is a first factor and the customer using a previously authenticated device is a second factor. By using additional methods of authentication, transactions can be done more reliably and securely.

1. A method, comprising:
receiving, by a device comprising a processor, a phone number from a bank client device associated with a user identity; confirming, by the device, the phone number is associated with a client account; verifying, by the device, the client account contains no linked devices; generating, by the device, a first one time password and a second one time password; sending, by the device, the first one time password to the phone number; sending, by the device, the second one time password to the bank client device; receiving, by the device, a password and the second one time password from the bank client device; verifying, by the device, the second one time password and the password; and in response to the verifying, creating, by the device, a new client account in association with the user identity.
