Temporary security credentials are short-term credentials. You cannot use them after the credentials expire.

Temporary security credentials are generated dynamically on request and you cannot store the temporary security credentials. You can request for new temporary credentials before or after the session expires.

By default, the temporary security credentials last for an hour. However, you can use the optional

DurationSeconds

parameter to specify the duration of your session. You can enter a value from 900 seconds (15 minutes) to the maximum session duration setting for a role. You can enter a value from 1 hour to 12 hours.
