+ | * Our results show that email account topologies are diverse, but that many include elements of line and loop topologies. | ||
+ | * Loop topologies are especially concerning, as they allow attackers who already have access to one account to easily gain access to a further account. | ||
+ | * We also found that users created other vulnerabilities in their topologies by placing the final recovery nodes in inaccessible accounts, or by using accounts owned by somebody else as a recovery option. | ||
+ | * Users also tended to keep accounts with physical recovery options (which could be strong recovery options) separate from the rest of the recovery topology. | ||
+ | * Participants were often unaware of the connections between their accounts and only realized during the study that there are recovery links they are not happy with. | ||
