# Renew Tickets

Renew a ticket to extend its usable lifetime. Each time a ticket is renewed, its lifespan is reset to the original length of the ticket. It can then be used until the new time listed in the "Valid Until" column in the main window.

## Renew tickets automatically

1. Open the Options tab in the main window.
2. In the Ticket Options panel, select the Automatic Ticket Renewal checkbox if it is not already checked.

Your renewable tickets will automatically reset their lifetimes before they expire, until the renewable lifetime of the tickets is reached.

Note: This feature only works while MIT Kerberos is active and running. This means that if your machine is in hibernation mode or if Kerberos is not running when it is time to renew your tickets, your tickets will not be renewed and will expire instead.
