Abstract

A rollover system is provided to facilitate transitioning of client devices in a shared account network environment, from an old password to a new replacement password. The switching of passwords may take place gradually during a rollout period for client devices without required downtime and reducing a risk of lockouts. During the rollover period, a prior salt is temporarily carried over to a new verifier for the replacement password. Two new verifiers are generated: a temporary new verifier using the old salt for verification during the rollover period and another new verifier using a different new salt for verification after the rollover period had expired. During the rollover period, authentication involves the use of the temporary new verifier with the old salt or by the old verifier and old salt of the prior password. After the rollover period, authentication is based on the new verifier with a new salt.
