Can multiple agents log in to a Zendesk account at the same time?

Can multiple agents sign in at the same time?

No. Zendesk is designed to allow one agent to work with one account. Moreover, the use of one purchased agent sign-in by more than one individual violates the Main Services Agreement. For this reason, each agent needs separate credentials to work simultaneously.
