Yes, it's possible! It's a database configuration - and think it's on "OSSYS_PERSISTENT_LOGIN” table.
You should ask OutSystems support team to help you with that - support @outsystems.com.cheers,Vera
Thanks! Support team confirmed that it is configurable through the database:
OSSYS_PARAMETER table 'OutSystems.HubEdition.RememberLoginTimeoutInDays' in the OSADMIN schema.
