In one embodiment, a method includes retrieving a previous communication associated with a user on an online social network, the previous communication having been made on a date in the past; calculating a distribution-probability score for the previous communication reflecting a probability that the previous communication will be shared on the online social network by the user; and sending the previous communication to the user, wherein the distribution-probability score for the previous communication satisfies a threshold.

A computer system receives a request to access a server. The request includes a first device tag set. When the first device tag set matches a previously assigned device tag set, the computer system allows access to the server without requesting full access credentials of a user. The computer system invalidates the first device tag set, and sends a second device tag set. When the first device tag set does not match the previously assigned device tag set, the computer system requests full access credentials from the user.
