1. A computer implemented method comprising:
maintaining, at a server system, credential information for users including a first user and a second user; receiving, at the server system and from a device of the second user, a request for an alphanumeric code to use in validating a credential of the second user; generating, by the server system, an alphanumeric code associated with the credential of the second user to be validated; storing the generated alphanumeric code in association with timing data that defines how long the generated alphanumeric code is valid; sending, to the device of the second user, the generated alphanumeric code; receiving, at the server system and from a device of the first user, a request to validate a credential of the second user, wherein receiving the request to validate the credential comprises receiving, at the server system and from the device of the first user, an alphanumeric code based on user input; identifying, by the server system, the credential of the second user to validate based on the request received from the device of the first user; determining a match between the alphanumeric code received from the first user and the generated alphanumeric code and that reception of the received alphanumeric code accords with the timing data that defines how long the generated alphanumeric code is valid; based on the determination of the match between the alphanumeric code received from the first user and the generated alphanumeric code and that reception of the received alphanumeric code accords with the timing data that defines how long the generated alphanumeric code is valid, confirming, at the server system, that the credential of the second user corresponds to a credential issued to the second user by a credential issuing organization; based on confirmation that the credential of the second user corresponds to a credential issued to the second user by the credential issuing organization, accessing, by the server system and for the credential of the second user, credential information provided by the credential issuing organization; and validating, to the first user, the credential of the second user based on the accessed credential information provided by the credential issuing organization, wherein validating the credential of the second user comprises transmitting, to the device of the first user; an electronic notification that the credential of the second user is valid. |
