Abstract
In embodiments, an authentication server interfaces between a user device with a self-signed certificate and a verifying computer that accepts a user name and password. The user device generates a self-signed certificate signed by a private key on the user device. The self-signed certificate is transmitted to a verifying party computer over a network. The verifying party stores the self-signed certificate with user identification data. The user migrates trust to another device by providing the root certificate and intermediate certificate as a certificate chain to a second device, which then adds a new intermediate certificate to create a longer certificate chain with the same root certificate. In subsequent communications, the verifying party receives a certificate chain including the self-signed certificate from the second user device, and matches that with the user identification data stored in a database.
