AnswerClick to flip back
A
They must be installed on every computer that the user wishes to work
💡 Explanation:
Digital certificates for authentication must be installed on every computer the user wishes to work from. This is a significant disadvantage because it creates management overhead - users cannot easily work from new or temporary machines without certificate installation. Unlike passwords or tokens, certificates are tied to specific devices. The other options are not primary disadvantages - digital signatures are not resource-intensive relative to modern systems, certificates are economical to issue, and they are highly reliable when properly managed.
