The key can handle as many credentials as you like since they are not stored on the token itself. So unlike other hardware that slows down with each new password added, there is no limit to GateKeeper. To add more usernames and passwords (Web/OTP/Winlocal/Maclocal/Domain), connect your token to the application and add them on the Credentials tab. The usernames and passwords are not stored on the token, so no worries if you lose one. Just have that key deleted on the Hub.
For any additional questions or concerns regarding proximity settings, computer locking, credential management, or compliance, please contact GateKeeper Enterprise support using the Support Ticket form on https://gkaccess.com/support/ or email firstname.lastname@example.org.
