• if the second token is a valid match for the first token, then linking the first profile to the second profile on the social network.

A computer system comprising:

• at least one processor;
• and
• memory comprising instructions stored thereon that when executed by at least one processor cause at least one processor to perform acts comprising:
• receiving a user input action instructing a first device to share information to link a first social network profile on a first social network and to link a second social network profile on a second social network;
• sending from the first device to a first social network service a request for a first token for linking the first user profile on the first social network;
• receiving the first token from the first social network service;
• sending from the first device to a second social network service a request for a second token for linking the second social network profile on the second social network;
• receiving the second token from the second social network service;
• sending the first token and the second token from the first device to a second device, the sending comprising displaying a tag on the first device, the tag encoding the first token and the second token;
• receiving a confirmation that the first user profile has been linked to a third user profile on the first social network, the third user profile being associated with the second device;
• and
• receiving a confirmation that the second user profile has been linked to a fourth user profile on the second social network, the fourth user profile being associated with the second device.
