This disclosure describes techniques to set up a user account, such as a single sign on account, on a new user device with the use of another device on which the user is already authenticated. The authenticated device displays a QR code that includes encrypted data that includes user credentials and optionally, other information such as wireless access point name and credentials. For example, the data is encrypted using a public key of the new device. The new device decrypts the data using its own private key. The described techniques eliminate the need for a user to enter credentials on the new device.
